I'm getting worried that my 3GS may have some real problem. This is the story, I hope you can help me
- Bought a 3GS with old bootrom second hand and worked fine for 1 year
- Last month GPS stopped working, did a network reset, got the phone stuck on a Apple logo reboot cycle. At that time the iBoot message was

- I ended up restoring the phone (v3.1.2 + blackrain and unlock)
- A week ago the phone start to freeze randomly even when its not been use
- I look in Apple Computer\Logs\CrashReporter\MobileDevice\iphone\Pa nics and finde several panics like this one

Any idea of what can I do here? I don't really know why the phone os crashing, but seeing these two errors (CXT not valid & panic on WMROAM) on different incidents makes me think that the phone might be broken

Any ideas on how to debug further?

Thanks
