Bluetooth SE K700i / Jornada 720 Email & Web problems

Hi

I have a Jornada 720 with Socket Bluetooth CF card (120G drivers) and
SE K700i phone on Virgin mobile. My phone works fine for sending and
receiving email and browsing.

I have bonded both devices and can dial up using BT. I can even get a
connection to GPRS by dialling *99# in remote ). I cannot for the life
of me send or receive emails or open up a web page.

I know the phone is configured correctly and use the same email
settings on my phone, desktop and J720 (which works fine with my Cisco
340 WIFI card).

Could some kind soul please talk me through step by step how to get
things working.

Regards
John
