Yep - exact same problem - bad load. WiFi startup seemed to cause reboot. Continued to recycle. I had to do factory reset to get it to work. Of course that blew away everything including my SD card (guess I should have removed - my bad.) Problem now is no screen rotation. Activate app - any one that rotates screen - say calculator - and screen will not return until until reboot. Even then - no rotation. Hope someone can figure this out!
Thanks for the update on this. Sorry it happened to you to. Tech support told me to do a reset on it, but now I just learned that my reset button doesn't work. Sigh... So I guess I have to do the hard factory reset. Sigh again. However, THANKS for the SD card heads up. I wouldn't have thought of it. I'll take wifi over no screen rotation at this point though. This is pretty annoying considering I didn't really care about the ICS upgrade until everything was ironed out. I guess I was a guinea pig.
