True to the company's motto, should our tipster be correct, the company has been working on something "quietly brilliant" for AT&T. 

One of our connects that works for AT&T has pinged us to let us know about an upcoming Android device.  Dubbed the HTC Aria, it will be unveiled at an event on June 7th (which oddly enough, coincides with WWDC).  Details are sparse, but we've been told that the unit will be running Android 2.1 with HTC's Sense UI. 

Our guess?  Verizon has the DROID Incredible, Sprint has the EVO 4G, and T-Mobile has the Nexus One, so it's time for AT&T to get something cool.  Besides, AT&T has already confessed to five Android devices (including at least one from HTC), so it falls right in line.

Stay tuned for pictures and additional specifications as we receive them!

Update: The Nexus One that supports AT&T bands is temporarily unavailable in Google's online store.  Coincidence?  Who knows.
