Just curious if anyone has messed around with the band preference settings on QPST. I changed it from PCS only (which was the default on my phone) to Automatic and now it's found a closer tower. Changing the PRL never found the closer tower. Haven't done much testing to check the voice and data rates but it does show up here: as being part of the PRL that I have on my phone.

EDIT: I just changed it back to PCS only then back to Automatic and now I don't get any data connection at all. First time I changed it it was pretty slow though, although I did get better service because I connected to a different tower...and the second time it couldn't find the tower it was connected to (using Open Signal)

Hmm, maybe you confused your tower? do you know how towers work?
there is a primary box and a secondry box, the secondary typically serves for routing
to the cheaper prepaid servicez i think such as locust h2o i dont remember but they suck really bad.
see ldpost i believe, although an unknow esn may be routed to thd american roaming network.
hence an esn of 000000 will be prompted to pay via credit card make a collect call =) of use a phone card
that phone can also be provisioned with nearly any #.
for example, I tested calling my sisters house and caused her own # to come up on caller id.
once this box had you the only way I know to return to the normal primary
box is to re-enter the a-key on your phone or call your provider claiming not to have a clue why your data is not working and.they will still end up having u reenyer
your akey -probably- you can find your akey(authentication key)
with cdma workshop (possibly)
but I gurantee the cave akey calculator will probably work
good luck

i do not know how to reenter akey on these phones at least in cyanogenmod
##akey# does not work
you may find the akey short code with cave and try entering it in cdma workshop
or flash stock rom if ##akey# asks for akey enter it reboot test, then return to your mod
this should register you correctly with the tower.
This brings me back to those old token days, I need to look into what those cool people are doing.
I once heard they did something I wad interested in checking out - setting up your own data service.
I can concieve this as possible with private towers on unused frequencies a list of which is somewhere online. but I would like to know how they had setup their own gateway
that would be ideal. free unlimited uncensorable fully conected data networks
