Hey, I was facing an issue earlier where I was texting and when I was done my text, I just locked my phone. Moments later, I decided to check my phone again to see if I received a text. When I did this, I realized my iPhone had a black screen (nothing on it). My power button and home button were not responding whatsoever. I figured out how to solve this (a reset did the trick). However, I am wondering why it occurs. Does anyone know why this happens? Note: I am running iOS 6.01 with Evasi0n's Jailbreak. The last app I installed was something from the Apple App Store (it is a game).
