My iPhone just recently stopped being touch sensitive to the bottom third of the phone, meaning that I cannot slid to unlock or press any of the main keys on the bottom such as phone and SMS. I called Apple and I am going to send my iPhone in but it is jailbroken meaning that my warranty is voided. Although I did restore it back to a new phone not as my backup and I was wondering if they will be able to know that it was modded. And if so, is there anything I can do to get it back so that I will be able to receive a refurbished phone?
