Before you attempt this, unless you live in these areas, if won't be very much worth it:
Although it isn't bad to have just in case. The PRL will connect your phone to Alltel towers if there are any closer to you, if not, it will just use a VZW tower.
/!\WARNING/!\: Doing *228 in dialer , will overwrite the PRL to the regular VZW PRL.
A stronger signal usually has big benefits, especially on battery life.
Unfortunately, it won't help some people. But still, it's always good to have.
1) Click Here to download PRL
2)Take this , and put it on your phone's sd card. Don't put it in any folders on your sd card, just leave it at the front.
3) Go to the dialer and write, ##778 and press call, hold and you should get a pop up.
4) Select Edit Mode, then enter 000000 (6 zeros) as the password.
5) Slide down to PRL, and press Update PRL. ( Please wait a while, it takes some time)
6)Once there, slide down the keyboard and you should see the Hybrid PRL file,press on it, and then press OK.
7) It should bring you to the menu you were before, press the menu button on your phone and select Commit Modifications.
8) The phone will update and reboot. Congrats, you flashed the PRL!
