| | 9700 loses BIS data when switching 3g to 2g

Thanks in advance for any help....first post go lightly!
I've searched google, blackberry, crackberry etc and no one seems to have had this issue.
I can connect to my BIS and browse fine when I'm connected to the 3G service, as soon as the handset swaps to a GPRS or EDGE I lose all data - email and browsing. If the phone is limited to 2g only then rebooted, or signal off then back on again, 2g connects fine.
GPRS/EDGE is provisioned for, and indicates on the screen in capitals.
I've changed to a 64K sim card, problem still exists.
I've tried going to Host Routing Tables and Resending service books. I've done battery pulls, wipes and reinstall OS
At a loss as to what is causing this. To top it off, I can browse on WAP via GPRS/EDGE even when BIS isn't connecting on 2G.
I've spoken with Vodacom Advanced data team, and other than suggesting a replacement handset they have no ideas.
I'm running a BB 9700, V220.127.116.113, Platform 18.104.22.168. Supplied RIM factory unbranded and never locked.
Currently using a Vodacom SA 64K sim card.
