Here's how it typically works. You flash the cricket PRL and then you should be able to dial *611 and hear, "Welcome to Cricket." From there you can activate the service over the phone or take it to a Cricket store and tell them it's already flashed. The PRL and ##Program (##7764726) menus make talk and text work on Cricket. For MMS and 3G Internet you need to change the NV Items, APNs, and M.IP/PPP passwords. After you get a Cricket account you'll need your MIN and MDN. The MDN is your phone number. This information goes under the User Activation settings of the ##Program Menu.
