Need Help with OS 6?

i also have a question i installed both the leaked versions of os 6 on my 9700 of t-mobile. But with both of them i had problems with instant-email and internet. messages, emails and bbm messages arrived very late. And i couldnt go on internet with 3G? any fix for this?

or anyone has a tutorial that explains installation of os 6 properly, and dealing with the issues noted above?

Definitely sounds like you did not backup and restore all of your service books prior to the upgrade.

Did you go into the service books menu and enable legacy books by pressing ALT-SBEB?
