My iphone 2G using firmware 2.0 keeps on turning off randomly. I will be in the middle of playing a game, watching a movie, listening to music or sending a text message and it will turn off! After reading the posts here I noticed that a lot of people have this problem too. I reseted the phone and did the jailbreak and unlocking again thinking this will help, but didn't. So today I made an appointment to go to the Genius Bar. I checked Apple online and it says my phone is still under limited warranty. My question is how can I get apple to fix it for free or give me a new iphone since I unlocked it and jailbroked it? Can I just delete cydia? Or do I have to delete everything b4 I take it to them or can I just leave it and take it? Thank you so much.
