Bell 6800 no internet

[aias]

Ok so my boss decided it was a good idea to try to get the GPS working on his Bell htc6800, which resulted in the phone getting stuck in the bootloader (Spl- 2.40.Olipro) I've since tried to install a number of ROMs to get it working again and i've had little success.. The Offical htc 2.17.666.1 Rom loaded fine but once it goes into standby mode it i can't get it out and have to do a reset. So i installed the Official Sprint one and now i can't get internet(data) although the phone itself works fine.

Please Help!
