I finnally took the plunge... Was sweating buckets for a minute.. but everything worked up just fine...
I had a bell mobility HTC touch with Rom 1.19 and radio 1.59.10a...
Went ahead and follow the exact instructions from this link.. (1 through 12)

Obvioulsty choosing the alltel with GPS...
Also note that I used all the files from those links too...
then I kept scrolling down to "GPS How-to" and follow steps 1 through 4....
And you know what... everything worked like a charm... JUST PERFECT....
Also note that internet worked all along after the unlocker then also after the alltel rom and also again after the JD'S room...
Again if you follow those instruction just as they are, you should not ran into any troubles...
Now as far as the GPS... again I open GPS viewer and after I see one or more sats under GPS Status tab.. I go ahead and open Google maps and what do you know...? IT works every time and is dead on to the square foot...
Really, really happy with this upgrade...
Hope this helps...
