I'm not sure how far I've strayed from what is officially supported, but here goes:
I'm using UMA on the Rogers network with an AT&T branded Torch upgraded to 22.214.171.124 (Bundle 695). To get this working I had to manually enter settings on the engineering screens under session manager. Everything works great, although calls drop if I walk out of range from the Wifi network. However, when the phone reboots after application updates or battery pulls, the UMA Protocol version defaults back to 1.0.3. The Rogers UMA support seems to only work with 1.0.4 and 3GPP rev 6. When I set the phone back to one of these settings, it works great.
Is there any way to get the phone to stay on 1.0.4 or 3GPP rev 6?
