Taken from the Touch Pro Essentials thread:

"To enter programming mode, open your phone screen and dial ##778# (may be ##778 on some devices, if that doesn't work, run EPST.exe from \Windows)."

i tried dialing both ##778# and ##778 and it doesnt work
i also don't have the EPST.exe file
i'm running an HTC Touch Pro i imported and im on the Rogers network.
any help would be appreciated cause my ringer is too slow, i need to speed it up.
