Could not use Google Local Mobile with T-Mobile

[giba]

I just switched to T-mobile (U.S) and signed up for their unlimited GPRS plan for my Series 60 phone (Nokia 6260). For some reason, all web sites access fine but I cannot use Google Local for Mobile. When I open the application, it prompted me to choose the Access Point, but the loading status just stay there forever.

Google Local used to work fine when I was using Cingular, on the same phone.

Any help appreciated,
Thanks,
