When I was in Las Vegas for OpenForce07 I got to talk to some of the folks over at AT&T wireless' developer program, DevCentral http://developer.att.com
I had signed up on their site LONG ago when I first purchased my MPX200 way back in the day, but never really took it anywhere. Well now that my Blackjack is working again (replaced by AT&T) I'm looking forward to diving into mobile device development so I've started digging around on the website a bit. It doesn't look, based on forum threads, to be all that active, but perhaps I can help change that. We'll see how much I can get going on my phone, though I'm really anxious to get the phone upgraded to Windows Mobile 6 (WM6) so I can be on the latest and greatest software.
