this has been posted on other forums but ill add the info here this will work on most blackberry devices

This isn't my solution, don't credit me.
First, go to options>advanced options>service books.
Hold ALT, and hit S/B/E/B(on the 8130 you have to hit S twice) to activate Legacy Service Books.
Make sure you have Desktop Manager. Download the service books here: URL
and restore the service book from desktop manager.
There you go. Full WAP and MMS on any Cricket flashed BB.
(Note: you may have to do a battery pull and reboot after you restore the SB)
