Hello all, I have just experienced this problem with my iPhone, I can slide to unlock it, but once unlocked, the bottom row of the screen doesn't work (Phone, Mail, Safari, and iPod.) So my question is that is there a way to change the screen's sensitivity through a Jailbreak, I have heard it being possible, but I just want to know what I have to do to get the sensitivity adjustment app. The iPhone is on 2.2.1 firmware and is in no way Jailbroken or unlocked. I am in no way new to Jailbreaking so if thats what it takes I am willing to do it. Please help me out Thanks!
