I was searching for a later Beta for my phone last night and ran across this link: BlackBerry 8830 OS 220.127.116.11 officially released by Bell » BlackBerry Sync | get in sync with the latest BlackBerry News
The title says it all!
It wouldn't install over the beta .101. I had to erase everything and reinstall the new OS. (BACKUP YOUR DATA!!! Delete the beta version from your PC, install the new OS on the PC. Connect phone and run the Application Loader.).
It installed smoothly and seems to be running well. All my data reinstalled from the backup when I ran the synchronization applet. I'm having to reinstall a couple of apps, e.g., the Google suite (which is new and improved!), my Bible reader.
I heartily commend it to your use!
