changing itunes account on iphone.
my friends battery was dying on his iphone and asked me to charge it, the only charger i have goes directly in my pc. when it connected itunes came and i made sure it didn't sync. two days later he has a app update and it won't let him update because my info is linked for itunes on his iphone .
