After having my iPhone since July, Apple had to replace it because half my touch screen wasn't working. I loved my original and had it modded just how I like it. My question is after doing some research on this and other iPhone sites I am reading a lot on how it may not be safe to mod phones that come 1.1.2 right out of the box. Can I or can't I? Is it possible to downgrade? I am seeing on other modding websites that there is currently no way to mod these phones. Am I S.O.L or do you experts know if it can be done? Please help me decide.
