Guys (and uncle benny), the above just happened to me again today

!!!! @#$#@%#^#!
This time I was in the cinema. Middle of movie, checked my phone, again the above happened with a missed call. Stupid weird 'bootlooping', touchscreen unresponsive at the Enter PIN page..............so i got home and tried to narrow down the damn problem.
It seems that there is a problem with missing calls on my phone (not sure if the problem is just on my phone or not). I restored using CWM and tried to test it as how I had been using it before the damn thing happened again. It's confirmed that everytime I missed a call when the phone is idle, the damn 'bootloop' happens, and there is no way to recover it, remove battery, restart phone. Had to restore/reflash the phone.
I'm on KH3 firmware from samfirmware.com and I dont remember this problem present on previous firmwares.
Just posting it here in case it happens to someone. Damn it , still a bit pissed off.

Edit:- 2.24am - Reflashed to KH1 firmware. Problem solved, missed calls doesnt 'bootloop' the phone anymore.
