I also have a Bell Touch that is unlocked and running SPL 2.31 with Jakdillard's clean and basic 6.1 rom as posted in this thread.
http://forum.ppcgeeks.com/showthread.php?t=24979 It is clean and efficient but not designed off the Bell rom. I am not missing anything from the Bell rom that I don't have on JD's rom. I did everything exactlty as laid out in the thread and I have both RevA and GPS working. The rom is faster all around then the Bell rom. The GPS locks within 1-3 minutes inside or outside. One odd thing is that all in coming and out going calls now use 1X exclusivly. Before it would switch from 1X to EVDO depending on my area. But the phone quality has not changed for the better or worse.
I love JD's rom and would never go back to Bells bloated and slow loading rom.
