Troubleshooting why my Android phone is rebooting (Nexus S) It seems to happen when I'm using Pandora. But then again, I'm always using Pandora. It also reboots so quickly that sometimes, I do not notice.

Is there a way to see what caused the last reboot?
Engadget has just reported that the Nexus S is having issues with random reboots (http://www.engadget.com/2011/02/15/nexus-s-suffering-from-random-data-loss-reboots/) and apparently fixes are coming.

To see the log you can get the following app:
