    Installed the new desktop 5.0 for BB and I get getting an 0x3b21 error when the phone is connected to the USB cable. Any thoughts?

    I just installed the 5.0.xxx DM on 2 pc's a week or 2 ago, and have no problems on either pc. If it were me, I'd try a battery pull (actually removing the battery for 1 minute) and reboot the PC first. If that didn't help, I'd uninstall DM, reboot the PC, delete the previous DM download, re download the latest DM and reinstall.

    I found to possible fixes to your problem. Both of them are related to synchronizing. You didn't mention if you were plugging the Blackberry in to sync or not, but the easy fix would be to disable sync if you're not using it. Click Synchronize, then uncheck the box under Synchronize Automatically. If you want to use sync, check the links below to resolve the problem:
