AT&T Starting WP7 Mango Updates Next Week?

We've all been waiting for some beautiful tiled Microsoft fruit salad, and a ripe new rumor says September 27th is AT&T Mango Day. According to WPCentral, citing internal emails,, AT&T customers will get Mango on the following handsets:

HTC Surround (SKU 65212)
LG Quantum (SKU 65205)
Samsung Focus (SKU 65203)

Unfortunately, things are a little complicated for the Focus—you might not get it based on how recent your hardware is, which will probably piss off and confuse a lot of people who don't know what a hardware revision number is, don't give a shit, and just want an updated OS like everyone else. Well, tough, it appears. But for the rest, the 27th might prove to be a very, very exciting day. As far as phone OS updates go. [WPCentral]
