I'm getting some serious lag when pressing my home button. I'm on ios5 jailbroken. Sometimes it's just unresponsive. Locking the screen then unlocking and tapping home works but it seems to be getting worse and slower. I did a tethered reboot and it seemed to regain a little responsiveness back. Any ideas why this is happening? A buddy of mine said that the home buttons will do this from time to time but it's more than likely a hardware issue. I'm looking for any and all suggestions. Thank you ahead of time.
