I've let the phone completely die but when I plug it up it does the same thing...I haven't had a chance to plug it up to a computer yet but I'm hoping I'll get the option to retire on there. And another thing is that my friend doesn't have her computer that she usually uses with her phone because it's a school laptop, so is there a way for me' to fix her phone on my iTunes without her losing all her data? I hope I can fix it because I'll feel like a jerk if I messed up her phone haha...Any help is appreciated. Thanks!
