BIS working but can't set up Email

Hello all

I've got an unlocked Verizon 9550 Storm 2 and I'm using a GSM only sim. I've got BIS working on the phone (3G with BB logo, service status shows BIS active). I can use BBM, Maps, Browser, etc on BIS or WiFi, but when I try to set up my email (and the 'Email Settings' icon is called 'default' for some reason), it says 'Device Not Registered' and asks me to register it from HRT in Advanced Options.

I do this, I get a message from Blackberry saying the device is now registered, there are 3 entries in the HRT option as well for GPRS and WiFi, but I still can't do anything for the email.

Any suggestions?

Have you sent the service books to the device?
