you got for Christmas? Already old news. Sorry. According to a report from BGR, the next iPhone will be out in the fall of 2012 and will sport a body redesign.
It appears the new iPhone will have rubber or plastic built into the front bezel that will connect the glass screen with the aluminum back, and the screen itself should increase to 4 inches. The antenna system will also get an overhaul, now surrounding the phone and making redundant the plastic insert currently above the antenna.
Presumably the next iPhone will have lots of other upgrades as well, but a body redesign couldn’t hurt.
