Untethered Jailbreak For iPhone 4 – Release Date May Be Delayed

Some bad news if you were eagerly anticipating the release of an untethered jailbreak solution for iOS 4.2.1. The iPhone Dev Team has hinted that this solution – that was initially expected to launch by Christmas – could be delayed by a few days. In a message posted on Twitter, Comex from the iPhone Dev Team has said that he might be missing the Christmas deadline.

While there is an alternative solution available – one that the Dev Team may release if the current release fails to work appropriately – that solution may not be ideal considering that it will require users to take an SHSH blob backup for iOS 4.2b3. Also, the solution from Comex is expected to come with a univesal jailbreak tool that could help all iDevice owners including iPhone 4, Apple TV 2G and iPod Touch 4G.

Untethered iOS 4.2.1 Jailbreak To Release Before Christmas

You must be aware that the present iOS 4.2.1 jailbreaking tool works best only on the older models like iPhone 3G and 3GS. While iPhone 4 and iPad users too may jailbreak using the available version of RedSn0w, these users will need to make do with a tethered jailbreak. That means, every time you need to reboot your device, you will need to plug the handset to a computer – something that is not very convenient if you are always on the move.

Earlier this month, we had heard from the iPhone Dev Team that an alternative untethered jailbreak solution was on the way and that this should be released before Christmas. Now, a couple of weeks later, we hear that the deadline still holds. In response to an iPhone owner, the iPhone Dev Team has responded,

@scotty6kids78 it’ll be here by Xmas (not because we’re sitting waiting for Xmas, but because it’s achievable deadline)”

So there you have it. You have at least one more Christmas gift on its way.

iOS 4.2 Bugs – iPad Wi-Fi Slow After iOS 4.2 Update

Bugs on Apple’s latest iOS seem to be cropping up one after another. We have earlier written about a number of issues users have been facing since they upgraded to the latest iOS 4.2. For instance, some found their music libraries go missing, others complained about their iDevice not being able to connect to their car stereo or to the 3G network.

Now adding up to Apple’s woes is a new issue with the iPad Wi-Fi network. A number of users have been complaining that their tablet is noticing an extremely slow Wi-Fi connection since updating to the latest iOS. A thread on the Apple support forums, spanning close to 700 posts has a lot of users posting about the issues they have been facing.

“My wifi is incredibly slow after I upgraded two of the three iPads in my home to iOS 4.2. The other iPad that has not been upgraded works fine. In a side by side test loading the same web page, the iOS 4.2 iPad takes 5x as long. Any ideas on why this would happen?”

“After iOS 4.2 installation the wifi connection is very slow. Unusable. Other mac and pc work fine on the same wifi lan. There are other posts on this subject, I believe this is a true bug.”

The issue is not with all iPads and the problem appears to be rather selective. In any case, if you have been affected, you may try out these solutions. Seems to have worked for some.

“I had the same problem with Ipad appearing to have a connection but IP is 169.xxx.xxx.xxx, Here is what I did that so far worked,been connected for 3 days straight now.

  • Reset/forget the network on iPad.
  • Change security on your router to just wpa2-aes only .( might have to retype your password again)save and restart router.
  • I’m not sure if I did a reboot on my ipad but wouldn’t hurt..find your netwrok and connect…that’s it.”

Or,

“I changed the passwords for my Main network and my Guest Network. After doing that, the utility instructed me to disconnect my modem’s power cord for a couple seconds and reconnect. I should say that I had already performed the disconnect of my modem’s power supply before. That accomplished nothing. The difference here was that I had changed the passwords of my two networks first.

If you read my last post, you know that I quoted terrible video performance for two specific apps…AppAdvice and MLB at Bat 2010. So, after doing the above I tried playing videos on both apps. FLAWLESS PERFORMANCE. OMG!”

Did these tips work? Tell us in the comments.

iPhone Unlock GPS Signal Issue – Fix For Downgrading Baseband Coming Soon

If you are one of those iPhone 3G or iPhone 3GS users who have been experiencing problems with GPS signal connectivity since unlocking your iDevice with the latest version of RedSn0w or PwnageTool, then some fix to the problem may be coming soon.

Folks at the iPhone Dev Team have indicated that they have been working on a solution that will let these iPhone 3G and 3GS users to downgrade their iPhone baseband from the new 06.15.00 back to 05.15.04. While there is no clear indication on how this works, we do assume that the baseband downgrade will still keep these iPhones unlocked.

You may recall that the latest iPhone unlock solution works by upgrading the baseband of the iPhones to the original iPad firmware that was seen to be vulnerable to an exploit. Now if the baseband is downgraded, there is also a likelihood for the phone to get locked back.

There is no clarity on this as yet. We will get you some more info when we get it.

Untethered Jailbreak For iOS 4.2.1 To Release Shortly?

In case you haven’t been following this space much, a jailbreak solution for the recently launched iOS 4.2.1 is already available and is being used by a lot of iPhone users. However, it is currently a tethered jailbreak which means users will have to tether their iPhone to a computer every time they need to reboot their device.

Comex from the iPhone Dev Team has revealed that his team has been working on launching an untethered jailbreak system that could greatly simplify the iOS 4.2.1 jailbreak process. This was revealed in a series of tweets posted by Comex from his account.

The new release can be used on the newer iOS models like iPhone 4, iPhone 3GS (with newer bootrom) as well as iPod Touch 4G. The presently available untethered jailbreak techniques are only available for the older models like iPhone 3G and iPhone 3GS with older bootrom.

We will let you know when this new jailbreak software launches.

Google Nexus S Vs. Apple iPhone 4 – Features & Pricing Compared

Google unveiled their new Nexus S smartphone yesterday. As expected, the phone will come equipped with the new Android 2.3 platform that has been dubbed Gingerbread. Like all other Google products, this one too is quite likely to be pitted against the iPhone 4. So which one is the better deal this season. We’ll take a look.

Nexus S Vs. iPhone 4

Tech Specs and Features

Dimensions : The iPhone 4 measures 4.5″ x 2.31″ x 0.37″ while the Nexus S measures 4.8″ x 2.48″ x 0.42″. So as you can see, while the Nexus S will come with a larger screen, you may also have to contend with a minor increase in thickness

Display : Apple has all along advertised the iPhone 4 for its best-in-the-industry retina display that packs 960×640 pixels. The Nexus S has a smaller display resolution at 800×480 pixels. But if you are talking about display size overall, Nexus S is better with a 4″ display compared to the 3.5″ multitouch display of iPhone 4

Hardware : Not much to choose from. Both the iPhone 4 and Nexus S are equipped with a 1GHz processor along with a 512MB RAM. The iPhone 4 comes with internal storage between 16GB and 32GB while the Nexus S has a built-in internal storage of 16GB. But unlike most other Android phones, the Nexus S does not have an external storage slot. That could quite surely be a deal-breaker for many.

Camera : Again, not much to choose from. Both phones come with a 5-Megapixel rear facing camera along with a VGA camera on the front for video chatting.

Battery : Apple wins here. One of the most advertised features on the iPhone 4 is the battery that is noted to offer up to 7 hours of talk time. While the Nexus One was noted to offer 10 hours of talk time, the new Nexus S on the contrary only gives 6 hours.

There are a lot of miscellaenous features that will be of interest on both phones. Google however has chosen to emphasize the new NFC technology on the Nexus S that will let users interact with RFID tags that you may find on t-shirts, movie posters, stickers, etc. You can quite surely expect a number of new apps and interactive ads that take advantage of this new feature to follow soon.

The Nexus S will be priced at $199 – the same as the 16GB iPhone 4. The device will be available from December 16 from Best Buy and T-Mobile stores in the US and from December 20 at Best Buy and Carphone Warehouse stores in the UK.

Personally, I do not find any big deal of advancement on the Nexus S that will make it my most-wanted phone. But that is not to say that Nexus S is a poorer choice than the iPhone 4 or any of the recent Android and Windows Phone 7 launches.

No More Apple iPad Camera Connection Kit Support For Alternate USB Devices

Apple introduced a dongle named the Camera connection kit along with the iPad back in April this year. This is a nifty accessory that lets users to connect their digital camera to the iPad in order to quickly import or browse images from a digital camera on the iPad.

As users who purchased the dongle have noted since then, the camera connection kit was also capable to connecting to other USB devices like the keyboards, microphones, etc. No longer. Users who have updated their iPad to the latest iOS 4.2 platform are reporting that the dongle is no longer capable of connecting the iPads to devices that consume more than 20mAh.

This limitation does not restrict the accessory’s original function that is to help users connect the iPad to a digital camera. But for those who were thinking of alternate use-cases, the dongle no longer seems to be a useful device.

iPhone App Folders Disappearing After iOS Upgrade?

Folks at TiPb are pointing out to a bug on the new iOS 4.2 that we first mentioned over two months back – app folders on the iPhone or iPad seem to disappear inexplicably bringing all the stored apps back on to the homescreen. Apparently, Apple has not addressed this issue with the several iOS updates that it has issues since June when this issue was first noticed.

While Apple continues to stay mum on the bug, we hear that updating all the apps and then syncing them with iTunes (updated to the latest version) should address the issue. Alternately, you can also try out the fix that we had suggested in our earlier article –

1. Connect your iPhone to iTunes
2. From the left menu on iTunes, right click on your iPhone model and select ‘
Back up‘. Wait for the backup process to complete
3. Now right click on your iPhone device on the left menu once again and select ‘
Settings‘. Here, pick ‘Restore‘. Please remember this is only if you also need a firmware restore (Applicable to those who have unlocked their phones). Otherwise, from the ‘Settings‘, pick ‘Restore from Backup
4. If the system tries to sync files, cancel the process. Wait for the restoration to complete
5. Now perform restoration once again. Remember to pick the backup file created in Step 2. Wait for the process to complete

Does any of this resolve the bug? Don’t forget to tell us in the comments.

How To Fix Battery Drain On Unlocked iPhone 3G/3GS

Ever since the latest iOS 4.2 firmware was released for the iOS devices, there has been a lot of talk about the battery life on these units. While on one hand, we have Nokia Siemens claiming that a new NFCD technology on iOS 4.2 should ensure optimal battery usage and thereby increase battery life, we have been hearing from iPod Touch users about the battery drain that their gadgets have been experiencing with the latest update.

It doesn’t stop here. A number of iPhone 3G and iPhone 3GS users who have unlocked their handsets with the recently released UltraSn0w 1.2 software have been complaining about the battery drain on their devices. Apple is not to blame here and the jailbreakers are currently working on a fix to this issue that is expected to be released over Cydia shortly.

Apparently, the issue is with the hacktivation process that allows users to activate their phones using PwnageTool or RedSn0w instead of an official SIM. If you are one of those affected by the issue, you can try out one of the following methods

Option 1 : Get hold of an official SIM from a friend and activate the phone normally with this SIM. Once it is activated, take it out and replace it with your replacement SIM.

Option 2 : A workaround is to install the SBSettings app from Cydia and use it to quickly toggle the 3G network to OFF any time you don’t need it. You can save a lot of battery this way.

Does iOS 4.2 Upgrade Improve Battery Life Of iPhone, iPad Or iPod Touch?

A question to iOS device users – has the battery life on your iPhone or iPad improved after you upgraded to the latest iOS? We had recently written about a persisting problem faced by iPod Touch owners since the iOS 4.0 update that caused the battery on their devices to drain out rapidly. The issue does not seem to have gone away with the latest iOS update either.

However according to a recent note by Nokia Siemens, the latest iOS update brings a new technology that was developed by Apple in partnership with the company that could improve the battery life of the iDevice to a great extent. Called the Network Controlled Fast Dormancy (NFCD), this technology creates an optimal interface between awake and sleep modes that will help in minimizing battery spent during network reconnectivity while also idling during user inactivity. The note reads,

All this disconnecting and reconnecting takes time and can cause a frustratingly slow network response. On the other hand, leaving the smartphone in an active mode all the time drains the battery very quickly. To overcome the problem Nokia Siemens Networks introduced a method that, instead of putting the handset into idle or keeping it always active, keeps the handset in an intermediate state. From here, a smartphone can wake up much more quickly and needs to send far fewer signals to and from the network to start a data connection. You get a fast network response and a longer battery life.”

We wonder how much NFCD has improved battery performance in reality. Comment on your experiences.
