Default Bes to BIS

Please Login to Remove!

I am new to this forum so I hope you can help me, I have been given a BB 7290 on BT mobile by my work it was connected to there BES server.

I have my T-mobile sim card working in it but how do I change the OS from BT to T-mobile and make it T-mobile BIS so I can use it with my T-Mobile email like it would be if I bought it from them.

Hope you can help.
