My experience upgrading from BB OS 4.2 to Desktop Manager 4.6 and BB OS 4.5 for BB Pearl 8100C by AT&T
Desktop: MS Vista
First, the new OS 4.5 is much better. Better aesthetics throughout, html email, better calendar colors (and although still know categories and filtering of categores, I was able to get a separate calendar for every email address that display in different colors and can be selectively hidden), and more contact fields. The problem is that some cellular vendors are still stuck on OS 4.2 and don't seem in any hurry to post an upgrade. Fortunately, you can use other OS 4.5 upgrades not specifically designated by your vendor. Read on.
First thing I did was goto the BB download site and download all the latest stuff specifically for my ATT Pearl (at the time of writing Desktop 4.6 and some version of OS 4.2). Then I tried to use the upgrade link from the blackberry.com homepage. However, after it installed it said I was running latest software. At the time, I did not know that you were supposed to remove the vendor.xml file in order to get around the vendor limitation (see below), but perhaps I could have done it here and restarted Desktop Manager.
Instead, I read this article which explained most of the basics to me:
This article has download links and an explanation on deleting you vendor.xml file from this folder, which is necessary to install an OS that has not been pre-approved by your vendor (i.e. AT&T):
C:\Program Files\Common Files\Research In Motion\AppLoader
I did a lot of reading and tried a bunch a things unsuccessfully and was about to give up. But then I rechecked this folder and the vendor.xml file was there again. Somehow, it got reinstalled so I removed it to another folder again. Then I started Desktop Manager and Voila!, a message popped up to upgrade my device. I opened up the Details or Options button to look through additional software. I was able to select Maps and other stuff that wasn't selected by default. Do a search for the application listed to see if it's something you may want. I think one of the techie sounding ones enabled me to use multiple calendars.
When it updated, it backed up and deleted the whole device. It took a long time to finish as the device bogged down. I now believe this was tracked to the micro memory card. As such, I recommend removing it before doing the install. After the upgrade, my device was painfully slow and would keep rebooting continuously. This stopped after removing the memory card. I believe this is due to the memory card scanning problem explained here:
In other posts, it has been suggested you just need to delete BBthumbs.dat, but I have not done this yet and am not using the memory card yet. But anyway, it seems clear (since my device is now working) that I can use a card reader to get my pictures, etc. off of it, then format it, and start fresh (or buy a new card).
Then, I restored my data to the device, which was saved here:
Blackberry Application data saved at C:\Users\XXXXYourNameXXXX\Documents\LoaderBackup-(XXXDateofBackupXXX).ipd
Use Desktop Manager Backup/Restore tool to restore the information.
Then I went through personal email setup again and resent the service books. This is necessary to get html working. See this site for information (Doc ID KB15254 on Blackberry.com support):
