Dell Aero is AT&T's second Android phone

Looks like Dell's finally entering the modern US smartphone market with a renamed Mini 3 called the Aero for AT&T. There's some serious Android UI skinning going on here -- it looks like a riff on what we've seen on the Streak / Mini 5 -- but that's all we know specs-wise at the moment. To be honest, we're somewhat concerned that this custom UI skin will be built on top of Android 1.5 or 1.6 instead of 2.1, and that AT&T will mandate a Backflip-style app lockdown -- until we get some hard details all we have is this pic and our usual hope for the future.
