This part in particular applies posted by John Clark BBF Mod:
PLEASE REMEBER TO BACKUP ANY DATA FIRST
Delete the vendor.xml located in c:\program files\common files\research in motion\apploader.
Now, download this file: http://www.myfilehut.com/userfiles/1...s/rim8700g.sfi
and replace the one located here: c:\program files\common files\research in motion\shared\8700 v4.......\GPRS\
Then open Desktop Manager and it should prompt you to upgrade. This should give you the latest software with the ability to turn off your data in the network page.
Hope this helps others as its helped me.
