Not only has the memory on my Tour gone from 75% to 40% after the update, but now my address book won't sync. Many of my contacts are repeating several times, and when I sync the BB with my Mac, I get this message:
The Address Book database cannot be accessed for synchronization.
For help resolving this issue, refer to KB19454 in the BlackBerry Desktop Manager Knowledge Base.
Okay go back to wireless update again and hit the BB menu, go to check results and it will give you the option to delete the old downgrade data. Do that and let me know youre memory now.
