Nokia lumia 900 95000NGN

 This machine has A big, quality screen, fluid and stylish OS and premium build are all sprinkled with Nokia's magic in a package that's made to impress. We've been there already - and we don't mean the review we have of the Lumia 900 for AT&T. After all, it's a Lumia 800 all over again, only the screen got bigger. And yet, we are delighted to meet this smartphone again - and we'll give it that, it looks stunning in white.

You'll also be happy to know that this time around we're putting the Lumia 900 to all our usual tests. AT&T's Lumia 900 was reviewed away from the office but this one will not simply walk in and out of our labs without getting a taste of our torture routine.

The newly announced Windows Phone 8 has given us plenty to look forward to, but a WP8 upgrade is not on the cards for the Nokia Lumia 900. WP 7.8 is coming later this year to all compatible single-core devices and it will be the last update they are about to get. Both Nokia and Microsoft promise to continue the support though they will most likely be focusing their efforts on multiple-core WP8 smartphones.
