This sounds incredible. Even after so many Quad-cores and dual-cores devices being available on Amazon and even after many weeks since release, Lumia 900 rules the top rated device list 🙂 Cyan is current topmost rated device  followed by the Black model.
What also looks like a great show by the Nokia flagship, is its being back to top on best sellers in AT&T list even after much hype created by HTC One X launch on AT&T. Great to see Lumia 900 not only holding its own but also outselling the quad-core Android flagship 🙂
