PPC-6800 Problem

[creglenn]

I have a mogul i had it flahed over to cricket yesterday and it worked fine until i downloaded the wm6.1 update and now i cant use the service. But when i call from my girlfiends phone i still have service.

But my question is why does my phone not operate on the cricket service and why can i not even call the sprint customer service or the cricket customer service. Plus my phone will not stop roaming.

I have searched everywhere and nothing has helped can someone shed some light my way before i go back to the place to have it flashed again. Thanks!
