Microsoft has been sending out Windows Phone 7 devices to some developers last weeks. The device in question being the LG phone we saw demoed already at MIX10, but now more refined and with later builds of the OS. The working name of the phone is Panther, but on the box it says GW910.
The responses regarding the phone has so far been pretty good, people are saying it still not feels ready for production but that it’s getting there as it’s much improved compared to the device demoed at MIX10. Regarding the WP7 OS they are saying everything is smooth and running pretty good. And the production pace for the WP7 team is apparently high as the phone is getting new builds all the time.
For a short tour of the first setup of the phone, see the vid below.
