please confirm this?!?! Update w/o unlocking?

[hjl47]

I was searching thru some of threads, found this one in the 'got my touch in the mail, wat should i do first' thread. I am new to ppc's and am not comfortable unlocking, flashing etc, however, if the steps mentioned below are indeed true, I wont have to unlock and flash. Please someone confirm.

If you're not comfortable unlocking your phone, YOU HAVE SPRINT AS A CARRIER, and don't want to run one of the custom ROMS, all you really have to do to activate GPS

1. download the RAR file that stevedog1 linked above
2. hook up your phone to your computer with your USB cable and let it sync
3. copy off any photos or other data that you have on your phone that isn't backed up because the installer will wipe it out
4. leave the USB connected and execute the EXE file from the RAR on your computer and do what the program tells you to do until it tells you it's complete
5. When the upgrade is complete, execute \Windows\PPST.exe on your phone
