Ok so after finding posts on how the screenshot app will cause your iPhone to flash black and white lines across your screen with the Apple logo in the background, i thought i had found my problem ...

I have restored and re-jailbroken twice because of this
once on 1.1.3 and once on 1.1.4.

The first time it just constantly did it, but on 1.1.4 is would do it after the apple logo goes away for about 5 seconds before going to the normal homescreen.
A few days ago i restored because i would get it every time i started it up for those 5 seconds trying to fix it. After the restore I didnt install screenshot again obviously, but everytime i turn the phone on i still get the black and white lines for 5-10 seconds before it goes away, and after past bad experiences it worrys me and it bothers me that some app is still causing this... i dont have any uncommon 3rd party apps installed so im trying to figure out what is causing this and try to fix it....

thanks for any help in advance.
