The other day we saw the Nokia Lumia 920 out and about in Washington, presumably being tested one way or another. Now it's the HTC Windows Phone 8X's turn.

Reader Rodrigo L. spied this interesting setup in downtown San Francisco this past Thursday morning.  From the photo we can see three HTC 8Xs and what appears to be an older Samsung make (kudos to the first of you who figure it out).

If we had to guess, this looks to be carrier testing with perhaps different variations on radio software for signal strength testing. We suppose it could also be for static photo taking but we're leaning on the first idea instead. 

Any carrier testers out there want to lend a hand on telling us what's going? Sound off in comments. Either way, only 4-5 more weeks before we're rumored to be able to grab this phone on AT&T, T-Mobile and Verizon.
