So, after my jailbreak my home button began to be unresponsive at times. Sometimes i have to hit it multiple times to exit an app, and multitasking is almost impossible. Naturally I thought I had a defective home button and restored it as new so that I could take it to the genius bar. I didn't get the time to make and appointment, and left my phone on stock iOS 5 for a couple of weeks and didn't have a single problem, but when I jail broke it again, the problem came back immediately. Any ideas?
