Upgraded to latest ICS and fell into problem of reboot loop, non-stop after 2~3 minutes post boot. Can't stop even turn off Wifi and put the phone in flight mode.

Apparently the issues related to SD card, it work just fine after SD card get removed. Need to diagnose further what is wrong with my SD card (or that is ICS nature???) Anyone experience the same and can give me some clue?

Note: Mine is Non-G version, virgin set.
