iPhone 4S Screen Blacking Out

Hi, recently I have noticed that sometimes when I am using my iPhone the screen goes black even though I was just using it (and I had not pressed power) and to turn it back on I either have to press the home button or power button and the screen will turn back on. I am jailbroken running iOS 5.0.1.

You've got quite a few tweaks installed there, so it could well be some of them not playing nicely together. Can you remember installing a tweak and then finding that the screen then started to black out?

If you can't hazard a guess as to what it is, I'd start removing most of your tweaks and seeing if it the black outs continue. Then if they go, start to add the tweaks back, one-by-one, to see if it's a specific tweak that is causing it.

No I can't remember it happening after one specific tweak, but I'll try that thanks.
