Sony Ericsson XPERIA X10 hits the FCC again, this time with AT&T's 3G bands

Yes, you might recall a version of Sony Ericsson's mighty X10 getting FCC approval last week -- but this one isn't quite the same. This time around, we've got WCDMA 850 / 1900 accompanying the quadband EDGE, which is heartwarming news for anyone on AT&T, Rogers, Bell, or Telus, though the complete lack of branding on the FCC's test unit leaves us to speculate wildly over which of those carriers (if any) will brand the unit -- and more importantly, whether any will be on shelves before frickin' 2011. In the meantime, we're guessing SonyStyle sales are a lock -- so get your save on.
