here is an excellent little cab i found over at the XDA forums. credit goes to ryanmogul for creating this cab, i don't think he ever posted over on these forums.
he actually created this for the PPC6800, but it also works on the Touch Pro, and i know because i use it on mine.
I used it when my MMS wouldn't work when i flashed to MightyROM6, i spent over a month looking for a solution and getting suggestions from people, but no one ever gave me a straightforward answer, and then i found this. which is awesome because it works with any room you use. i used it on mighty rom, now i've switched to EnergyROM warhawk (best ROM i've used so far) and it works there very good too, so enjoy!
so the cab basically sets up your Arcsoft MMS settings for cricket, and it also goes ahead and sets up your WAP settings. so this is much better than dcd's cab for cricket. enjoy.
NOTE:
since it changes the Arcsoft MMS settings, you FIRST need to run the Arcsoft Removal cab, THEN run the Cricket WAP & MMS settings cab.
once you have done that, just try to go to the internet first, it'll ask you for your username and password.
Username:
your-10-digit-phone-number@mycricket.com
Password: cricket
and once you have done that, your internet should be working, and your MMS (picture msgs) too.
works on all ROMS, and WM6.0, 6.1, 6.5
hope this helped ya'll!
