^Thanks, Khan. I didn't get to that one. I checked Crackberry and the blackberry official forum. Those people didn't make it easy. The easiest instructions I found was on the Tmobile forum, to reinstall the OS, because my BB basically could not reboot at that point.
Should have tried that route first (the one in your link) before the wipe, but oh well. Too late now. I didn't think the OS reinstall would wipe out my contacts info, and I thought I had at least one backup file.
Lesson learned. These tech devices are not invincible, and back them up regularly.
Iris, I've had a lot of problems with it, and I don't even use it extensively. Today I was only trying to install an application, and apparently somehow it got corrupted, and when I tried to delete it, it probably took some parts of the OS along with it, and then I ended up with a corrupted OS. I wonder if maybe the fact that I have poor reception at my office has something to do with it. I often try to download apps or use apps when I'm in the office, and the poor reception occasionally caused the download to be interrupted. I had a corrupted facebook database file that caused me to get error messages before. I managed to fix that. And now a corrupted app caused the OS to crash.
I'm gonna try to see if I can get some kind of upgrade discount from Tmobile to get one of their 3G BBs even though I'm not technically eligible for an upgrade yet.
