A colleague of mine reports that last night when she took the Charm City Circulator to Federal Hilll, she couldn't reach the service's web site from her Blackberry. When she Googled Charm City Circulator and clicked on the link, her screen came up purple and did nothing.

I just sat down with her, Blackberry-to-Blackberry, and retried  the web site simultaneously. I had no trouble getting tthe Circulator's NextBus function (though I can't vouch for its accuracy). She could not. The difference: I was on the Verizon network, she was on AT&T.

So what gives here? Is this an AT&T issue or a city Department of Transportation issue? Is there a geek in the house?
