TomTom One LE from Bestbuy and Alltel

[mobilemedic]

Ok I just bought my tomtom excited to use my phone to update traffic and such..

Well I found a cab file on xda dev's site to get DUN working.. but.. still i cannot get it to sync up....

What are the settings to get Alltel setup on TomTom. My Phone is the PPC6800 (HTC MOGUL)

Please any help appreciated.
