iPhone 4 Unlock Releasing After iOS 4.3 Roll Out

Bad news for those of you intently waiting for the iPhone 4 unlock tool to be released. The iPhone Dev Team has clarified that an unlock tool for iPhone 4 shall not release until the official roll out of iOS 4.2.5 or iOS 4.3 – whichever is the latest. In a tweet to followers, jailbreaker MuscleNerd wrote,

“Official iPhone unlock statement: no unlock will be released until after 4.2.5 or official 4.3 (whichever is last) is out”

This should come as a huge disappointment considering that we had heard from another jailbreaker a few weeks that promised an unlock solution by this week. You may remember that Dev Team member Sherif Hashim had revealed back in December that the application should be out latest by January 16.

While this is definitely bad news, this was not entirely unexpected. Apple is expected to roll out iOS 4.3 within a couple of weeks from now – the beta version is already out with developers. Given that this new version could possibly patch the current exploits, it does not make much sense for the Dev Team to roll out an unlock tool only to get blocked a couple of weeks later.

New Sn0wBreeze iPhone Unlock Tool To Restore iPhone Without Baseband Upgrade

Popular iPhone developer and hacker, iH8Sn0w has spilled the beans on his upcoming project – Sn0wBreeze 2.2. The new software application, that is still in development mode will let users unlock their iPhone 4, 3GS or 3G running iOS 4.2.1 with the help of the UltraSn0w unlocking tool. In a tweet posted recently, iH8Sn0w has posted the following teaser image of the upcoming tool.

Sn0wBreeze 2.2

The new version of Sn0wBreeze is expected to come with a new option called ‘Basedband Preservation Mode’ that will  let users restore their iDevices to iOS 4.2.1 without having to upgrade their baseband. There are also other modes like Simple Mode and Expert mode that the user may employ to create custom firmwares without the need for upgraded baseband.

There is no news on when the new Sn0wbreeze version will release. But we will let you know as and when that happens.

iPhone 4 Unlock Release Date Less Than A Month Away?

iPhone 4 users looking for a way to unlock their device may not have to wait for long. According to a tweet posted by Sherif Hashim, one of the prominent hackers from the iPhone Dev Team, the unlock tool should be released in less than a month’s time – at least before January 16.

It is not clear if this new unlocking solution will be based on a new exploit or if Hashim will make use of a baseband exploit that was discovered sometime back. As you may recall, this exploit can be used to cover all basebands – including versions 02.10.04 (that is incorporated on iOS 4.1) and 03.10.01 that is bundled with iOS 4.2.1.

Last month, we had reported about the release of UltraSn0w unlock tool. That, however, only worked with the older iPhone models like the 3G and 3GS. So if you are an iPhone 4 user who is yet to break away from your contracted carrier, the time to do it should come soon.

Legally Unlock iPhone With $50 Fee On Rogers/Fido In Canada

Rogers Canada has announced a new device unlocking policy that makes it possible for iPhone and several other mobile phone users to legally unlock their device by paying a $50 unlocking fee. To be eligible for such an unlock, customers must have their account in good standing, should have paid the unsubsidized cost of the device at least 30 days prior to request or at least have fulfilled the contractual obligation.

Such customers may contact the Roger customer care at 1-888-Rogers1 and request an unlock. Do note that there is also a tax on top of the $50 and so the actual amount you will need to pay for the unlock will vary between $52.50 (for Alberta) and $57.75 (for Prince Edward Island).

Once the unlocking is done, the customer will have to restore their device by connecting to iTunes and the unlocked handset should be ready for use.

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.

New RedSn0w Jailbreak Tool Hactivates iPhone Without Stock SIM

iPhone users looking to unlock their iDevice for use over alternate carriers normally perform a procedure called hactivation. This procedure lets you sign up to iTunes with a SIM from an alternate carrier thereby letting you use your unlocked iPhone. However because of the patches required, such a process often leads to battery drainage as well as iPhones getting hot pretty soon.

Now Sam Binger, the developer of TetherMe has released a new software that provides an amazing alternative. Called Subscriber Artificial Module (SAM), this alternate method tricks iTunes and iPhone into generating official activation tickets even though the unlocked device carries an unofficial SIM.

To make the process much more simpler, the iPhone Dev Team has now incorporated this technique into their latest RedSn0w jailbreak tool. With this new update, users jailbreaking their device may directly hactivate using SAM instead of the conventional method making the whole process seamless. However, for optimal usage, users will have to first deactivate the existing patches before signing in using SAM. The new RedSn0w update contains a “deactivate” button to easily perform this function.

You can check out the update from iPhone Dev Team here.

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.

Chevron WP7 Unlocker Tool Pulled After Microsoft Negotiations

The iOS jailbreak community has often been viewed as rebels who have challenged Apple’s attempts to curb the limitations of the software. Apple’s strategy to deal with the jailbreakers doesn’t seem to have impressed many as the two have been engaged in a cat and mouse game as far as jailbreaking is concerned. With the release of ChevronWP7 unlocking tool for Windows Phone 7, one may have been anticipating a similar reaction from Microsoft. Apparently, Redmond seems to have learned from Cupertino’s mistake as the company has embraced the concerns of the jailbreak software developers.

In a blog post, ChevronWP7 developers have announced that they were contacted by Microsoft director of Developer Experience, Brandon Watson who agreed to open the Windows Phone 7 platform in order to allow greater access to developers and users with respect to homebrew opportunities. Following these discussions, the developers have decided to pull the ChevronWP7 tool and cease further development work.

It is not clear what path this amiable resolution will take in the future. But at least it appears to be the right move from Microsoft so far.

iPhone Unlock Causing GPS Crash & Signal Issue

The iPhone Dev team recently released the latest unlocking tool for iPhone 3G and 3GS devices running the latest version 4.2 of the operating system. The unlocking solution was made possible with the help of a known exploit that the iPad’s original firmware was learned to be still vulnerable to. You can read all about the unlock in our earlier article here.

Since the release of the unlock, several users have complained that the application seems to be breaking the iPhone’s GPS software. Users have noted that the unlock either causes the iPhone to crash or cause the GPS to lose signals. In an update to their announcement, the iPhone Dev team had noted,

“Unlockers have been reporting mixed results about GPS functionality at 06.15.00.  Until we can track down what differentiates those who retain GPS vs. those who lose it, be conservative and assume you’ll lose GPS at 06.15.00.  As we work on finding the cause (and possibly a fix), please report your personal findings in our comments section. (Update: early indications are that while 06.15.00 is capable of GPS, it will require some further hacks.  But please still be conservative and assume you will lose GPS at 06.15, in case the hacks don’t work).”

Apparently, the team is still at work at deciphering the missing links and notes that the issue is not due to the limitations of 06.15. In a recent tweet, popular jailbreaker from the Dev Team, MuscleNerd has written,

“We’re working on a fix for those who see the problem (it’s not a limitation of 06.15, we know that much)”

We will let you know if and when a fix becomes available.
