Hi, we got our test P910i connect to our BES, but we haven't been able to browse the internet with it. We've got a AT&T SIM in it, what settings and where should I set? I thought I'd be able to browse through MDS since we are on a BES, but it's not working.

I had that problem with my 6822 from Nokia. You have to call up your service provider and tell them to provision the service as a none BB hardware. I think that's because P910 will use Mmode as GPRS and not BB. I hope that works for you.
