iPhone 4G Features Leaked?

Did the tech specs of the next generation iPhone just get leaked? I am not sure, but I hope these are true. Here are some tech specs that is speculated to come with the iPhone 4G aka iPhone HD

Resolution : 960 x 640 pixels
CPU : In-house A4 (like the iPad)
A second front facing camera
iPhone OS 4.0
End of exclusivity and a new Verizon based model

While the specs are definitely interesting, it is worth a note that a better display on iPhone could actually cannibalize the sale of iPad. That is however, only if the iPad fails to carve out a niche for itself in this period. This is one gamble, Apple could be taking.

Multitasking On iPhone To Come With OS 4.0

Multitasking, the simple process of being able to toggle between two or more apps may finally come to the iPhone. According to reliable sources that Apple Insider spoke to, Apple shall be incorporating a “full on” solution that will finally enable multitasking without drastic drop in battery performance. Apple Insider writes

“From a user-facing perspective, Apple plans to deliver a multi-tasking manager that leverages interface technology already bundled with its Mac OS X operating system, according to those same people. It was requested that specifics be withheld at this time, as the iPhone Software 4.0 remains under development and reportedly has a quite ‘way to go’ before it’s ready for prime time.”

Multitasking has been one of the most vocal demands from iPhone users (Adobe Flash, front-facing camera, transparent app store policies etc. being a few other things) who want to have greater freedom on what they would like to do on their iPhones without having to deal with the Apple police.

However, disclaimer’s that this is still a rumor and the ball is still very much in Apple’s court over whether this will finally be implemented.

iPhone OS 4.1 To Unify iPhone With iPad

Despite running on the same OS, the iPhone and iPad are caught up in different versions, each incapable of being compatible with the other. While iPad runs on iPhone OS 3.2, it is being speculated that the next generation iPhone shall run on iPhone OS 4.0; which is expected to be launched in the summer of this year.

According to a recent report on the Loop, the period between the launch of the iPad and iPhone 4G is not sufficient enough to expect an iPad compatible iPhone to launch. This could mean that an OS compatible with both iPhone and iPad could launch not earlier than the iPhone OS 4.1 version – expected by the end of this year or early next year.

While this is purely speculation on part of Loop, we are quite skeptical. For one, the iPad has been in the making for quite sometime and it is likely that the iPhone OS for the next generation iPhone has derived a lot of technology from work done for the iPad. This leads to a possible unification as early as June of this year.

What are your thoughts?

iPhone OS 4.0 To Be Launched March 14?

Redmond Pie is quoting an anonymous tipster to have written to them that iPhone OS 4.0 shall be launched on March 14. However, as the website notes, March 14th is a Sunday and traditionally Apple has not launched any of their products on a Sunday.

That being said, we would still like to hold on to the rumor. With the launch of iPad scheduled for the end of March, a mid-March release of iPhone OS could provide the impetus that Apple would desire ahead of the tablet’s launch.

What are your thoughts? Do you see any truth in this rumor? Tell us what you think.

Apple To Let Push-Button Based Location Sharing Feature On iPhone?

There are patents aplenty on letting users know if any of their friends are in their vicinity based on GPS information. While that is certainly cool, it is not particularly useful. Here is a nifty new feature that one might get to see in future versions of the iPhone.

In a fresh patent filed recently at the US Patent and Trademark Office (USPTO), Apple has described a technology that will help users send their location details to their friends at the push of a button. Alternatively, users may also request for location information from their friends.

This can be pretty useful if one of your friends is lost or feels the GPS is not particularly helpful. With a lot of location related patents being filed by Apple of late, it is to be seen how the company plans to integrate all these services into one comprehensive location tool. It will be interesting if we get to see some of this in iPhone OS 4.0.
