Not getting internet connection

[sailor1960]

I can't get on the internet after all this ROM changing.
It does dial the #777 as before.

It thinks it needs a username and password to get on the internet.
As well the Current username comes up with the right ESN# but with sprint at the end of the name.

I have tried to revert to the orig ROM, Bell 1.19XXXX from the Sprint 3.XXX
The current SPL 2.31.Coke CPLD-3
Upgraded from the orig to 2.0 then went to this 2.31
What I was trying to do is update the Radio and get GPS to work.
I saw a limited use come up. But the phone was All Sprint.

VOGU100
MSM7500-400Mhz
WM 6.1 CE 5.2.19208.1.0.1
ROM v1.19.666.1 Jun 30 08
Radio v3.42.30 HW v 0001
PRL 31398
PRI v2.04_003
ESN 36AXXXXX
Current username 36AXXXXX @hcm.sprint......

Any suggestions? Help with either getting back the internet first.
Or reverting to an operable ROM 1.19.666.1
I have the entire phone backed up. Contacts, other stuff works okay.

Disregard, just got the new Bell ROM download from HTC site. It did load over the other one. GPS on Google maps works, but now the phone keeps loosing service and contacts list won't come up.

Did you run Bell Customization?
I had noticed that after flashing PRI wasn't changed.
Only after Bell customization PRI 2.04_003 had been changed to PRI 2.02_007 on my phone.

PS:
I have just bought the Vogue, will have European carrier. Have a dilemma what to use:

1. Bell 3.42.50 radio with Bell PRI 2.02_007 (Bell firmware defaults)
2. Bell 3.42.50 radio with Sprint PRI 2.04_003 (you can get this by flashing Sprint and running Bell without customization)
3. Sprint 3.42.30 radio with Sprint PRI 2.04_003 (Sprint firmware defaults).

GPS work without carrier network (e.g. without A-GPS) is very important. Can anyone suggest?
