Neutron said:Its gonna be expensive for those of us currently in contracts. I doubt the wireless carriers will make an exception like AT&T did when the 3GS came out and allowed those with a 3G that got them the year prior to upgrade early.
The battery in my 4S is showing signs of not holding a charge like it did when I first got it but that's to be expected.
If you're having battery issues after less than a year, I would contact apple to see what they can do.
