Nokia is aiming for a November 2nd launch of its flagship Windows Phone 8 handset in the US. Multiple sources familiar with Nokia's plans have revealed that the company is currently working with Microsoft and AT&T to complete a number of tests required to sign the device off in time. Microsoft is said to be close to finalizing its Windows Phone 8 software, with a Release to Manufacturing (RTM) due next week.

AT&T is currently testing the Lumia 920 in its labs, with a view to launching it on November 2nd, we're told. Microsoft is tentatively scheduling its own Windows Phone 8 launch plans for October 29th, just a few days before the expected launch date for the Lumia 920. The November 2nd date isn't set in stone, and there's potential for the date to slip further into November if any issues arise during carrier testing, but don't expect to see the Lumia 920 on AT&T before then.

Note: We originally published this story as an exclusive, but TechRadar previously rumored the November 2nd date.
