iOS 4.2 GM version is already released and final version is being expected next week but after every new update some features are dropped off for old models of the iPhone and iPod Touch.

Hardware is the main problem due to which old iPhone models can’t support the new features properly like FaceTime, HDR Photography, Multitasking etc. If we compare the hardware of iPhone 3G and iPhone 4, the former is about quarter of the latter.



You can see how well iPhone 3G is performing on iOS 4.2 while typing, zooming, scrolling, opening apps, etc. Moreover, iOS 4.2 should be released sometime this week. Stay tuned to Mod Your Pod for more updates on the issue.
