It's a network thing. AT&T cycles through different radio states when you're not explicitly sending/receiving data. They're called FACH, DCH, PCH, and IDLE. The radio firmware will try to keep the WWAN connection idle as much as possible because it saves battery, and when in the IDLE state it drops down to HSDPA only (3G).
