Motorola

Afternoon all. Need a little help. I have a customer who activated a v.300. I think it was an unlocked version from overseas or an unlocked t-mobile version. Normally I would go to the browser then web sessions and create a new profile and just copy the cingular setting into it. When I get to the screen for web session there are no choices. Does this mean that this phone is locked to a Carrier. Any ideas? From what I can figure, it is sim unlocked, but branded to a carrier or somehow restricted. I know that attws has the support site that will just blast the setting to the phone in a text and then just let you save them. Does Cingular have a similar option?
Thanks
