Alright guys, I need help.
so heres the situation:
i bought an iphone from some chinese phone store about half a year ago. I unlocked the phone and jailbroke it to work with t-mobile and get free games through installous. after a while the silent button wasnt functioning as it should and dust appeared under the screen. so today i tried to open it and fix the problem, i was so dumb to do that. i accidently pressed on the screen and cracked a corner of it. now the whole screen is black and the corner is black and i cant see a thing. my iphone is still under warranty and i would like you guys to help me with some questions i have.
1. if i backup and restore my iphone to factory settings, will apple find out that i jailbroke it and unlocked it.
2. do i need a at&t prepaid card to get a new iphone? if so, how much is the lowest payment and how should i do it?
3. can apple tell if i opened the iphone? if they can then will it affect the warranty? what if i just tell them i tried to fix it myself?
thank you so much for viewing and trying to help.
all help is appreciated. :o
