If he already has a GPS enabled radio (3.43.02) there is no need to go backwards. What is your bootloader. Put your phone in bootloader. If your spl is 2.40 or 2.47 then your are unlocked and you can go ahead and flash a custom ROM. The one I posted is pretty light weight and can be ran from your SD card or with a RUU that can be found in the FTP.

If you are not unlocked then go get the 2.47 and put it on your card and run it from the card. You can use the same method, put it on card and rename it TITAIMG.nbh and let it run. After you have unlocked (spl = 2.40 or 2.47) you can then load a custom ROM. Good Luck,
