i have an hardware unlocked iphone 1.1.2 OTB original but i have 1.1.1 on it with t-mobile. i understand theres a way to upgrade to 1.1.3 and keeping the phone unlocked well is there a way in which i can keep all my stuff that on my phone so it does not whip it? like apps and phone numbers will they be erased? or will it be there?
04.01.13_G firmware :D
