This is to make it so the Internal GPS works on an Alltel ppc-6800, without using hacked roms. unlock tools or anything along those lines. its an official ROM that has a small patch.
Make sure you have updated your ROM with the HTC/Alltel ROM from the website and the patch.
ROM:
http://216.139.227.226/alltel/RUU_TI..._PPST_Ship.exe
50MB
patch:
http://johniii.tripod.com/Enable_GPS_Alltel_ppc6800.zip <--must copy and paste into browser
80KB
1. copy the contents of the 'Enable_GPS_Alltel_ppc6800.zip' to your phone.
2. Install each of 4 files one at a time to the main memory (do not install on storage card).
3. start with file 1 then 2 then 3 then 4 (some of the install files will only make the screen 'flick' this is good. move on to the next one)
4. after they are all done soft reset the phone.
check that ur gps setting:
start/settings/system/external gps
Program Tab: Com 4
Hardware Tab: gps hardare port= none, baudrate = 4800 baud
Access Tab: check 'manage gps automatically'
use google maps. (gps option = let windows manage my gps)
------------------------------------------
As with any ROM upgrade, make sure you *228 and "upgrade your phones roaming capabilites"
*UPDATE*
