Where do you get PRL files

[KoTToN42e]

I am flashing my EVER frist phone.

Hello i need help!!!!

Where do you get or how do you write or what do you do to get a CRICKET OR ALL OF THEM PRL file for a HTC Touch PRO 1.

I am really having a hard time understanding what the "Cricket PRL files" are and how to get or write them. Do i need a certain one for the STATE OF COLORADO?

Also: what is the RIGHT PRL file to use for the HTC TOUCH PRO. I AM USING QPST.

Also: How do you get everything to work on the phone such as EMAIL/TEXT/MESSAGING/NAVIGATION?

thanks for all your help!
