I'm aftraid this is going to happen again in November when Lumia 920 comes out!
Thanks for asking this question. Was wondering the same thing. Can't believe some #$%$ thumbs downed your question lol.
they tried but it did not happen. Or Iwould say u tried but nokia will survive.
I guess folks correctly figured out that the Lumia 900 was not "Teh iPhone Killer™" fanboys made it out to be. The hardware was great but WP was still not ready for prime time and certainly not up to the task of competing with Android and iOS.
Nokia may intro other new models by then! One that has similar demensions to the new iPhone5!
Iphone 5 dimension is sucks. Go and buy ur iphone 5 now.
