Here's a quick way to find a lot of useful info on your BB. Alt-shift-h. Hit and hold these three keys in succession then release.
A screen entitled "Help Me!" will be displayed. Some of the info you will find: PIN, IMEI, uptime, battery level, which OS you're running, and amount of onboard memory available.
Try it out. And don't forget to answer the poll question and enter the wallpaper shuffle contest!
