from the Q tutorial (off the top my head):
Use CDMA general and write Simple IP as well as 1041 Cricket PRL...
I always manually NAM program these after changing ESN with Cricket
If you still have "Americas Roaming" you did something wrong...
also... check the Q thread and possibly post in there. Usually, opn this firum, you will gets lots more help if you post in the correct thread/forum instead of asking basic questions that have already been addressed. I would highlky doubt that someone will call you to walk you through it as the majority of every possible scenario has been posted/solved on here already
