My pearl is broken and I need to send it in for repair. I have loaned a T-Mobile BIS Pearl, and want to use it while mine is in repaid (I am on BES).

T-mobile did something special settings wise (APN), and I was told I couldnt use a BIS pearl on BES. So I downloaded and installed the latest software on it in the hope of removing these customisations.

I just tried enterprise activation and the device says: no networkconnection available. (I can call and surf by the way). Any clues on how to get this going?
