iPhone randomly shutting off

[salilsundresh]

Occassionally, my iPhone randomly shuts off and then I try to turn it on and it turns back on for a second or less and thaen shuts off. (by shuts off, I mean the screen goes off) Finally, after this happens 2-3 times I am able to turn it back on. Any ideas? I'm using firmware 1.1.1 unlocked with T-Mobile sim card.

I am having this same issue like crazy now. Started 2 days ago and seems to be getting worse. My phone is un-hacked. Any one have any ideas on this. I am going to do a restore this morning to see if that helps.

Thanks

My iphone started randomly shutting down, and sometimes it would take hooking up to power (usb) to get it to re-boot. The only thing I had done was upgrade cydia, so I went back and re pwned my phone and this time did not upgrade cydia (later on the phone). You need to re-install cydia back when you pwn or the new version stays on your phone. The problem went away! Hope this helps someone.
