I'm on Bell and here's what I did:
1. Upgraded to the alltel ROM posted in the sticky "
Upgrade Sprint Touch to Rev. A. COMPLETE TUTORIAL With Download Links"
2. Upgraded to the Titan 3.35 Radio just for kicks. (not required)
3. Installed Ghetto's V7.00 ROM - pretty close to a Bell Stock Rom
Everything works. I noticed my download speeds haven't changed. Still getting 800kbps - 1000kbps download as before but not sure if I'm in a Rev A area (Vancouver).
NOTE: Gps did not work right off the bat. It would not find any satellites no matter how long I left it on my porch. Google Maps wouldn't even show the blue dot that everyone here is talking about. I thought I did something wrong and was about to redo everything and then I remembered that there was a Location Setting in the Phone Setting that was either ON or for 911 only. I found that it was for 911 only so I changed it to be ON. From that point on, the GPS worked. even got the blue dot in Google Maps.
My average lock times are about 2 minutes.
