I went ahead and unlocked it and flashed it with
OMJ's 3.03, 3.09, M2D WM6.1 Custom Touch ROMs w/ User Customization
and installed the cricket cab. Phone and text work but no data. The cab file didn't really seem to change anything. She is happier with the touchflo interface though. Thanks for the link, i will check that out. It's still tries to dial #777 for sprint data so there must be configuring to do there. Thanks.
