Nokia Lumia 920 vs Lumia 820 comparison

AT&T announces last week the Nokia Lumia 920 is exclusive, and will be launced in November with the Lumia 820. The Lumia 920 will be available on AT&T exclusively according to the carrier. This in red, black and white colors, and through online orders in yellow and cyan colors. The Nokia Lumia 820 will be available in black only, but AT&T will stock additional colored shells. There's no word on pricing or exact availability for both models, but AT&T says they'll be available in November.

Searching on the web I found a comparison for Nokia Lumia 920 vs Lumia 820 with Windows Phone 8. Here it is:

In Europe the pricing will probably be 649 euro (Lumia 920) and 499 euro (Lumia 820) at Vodafone, T-Mobile and O2/Telefonica. More on this later when final pricing is available.

Update 8-1-2013: The Nokia devices are available for pre-order in The Netherlands.  The final pricing will be 599 euro (Lumia 920) and 499 euro (Lumia 820). The Lumia 620 will be just 259 euro. Nice to see that the Lumia 920 will be priced 50 euro less then expected!

Update: Have a look at Nokia Lumia 620 specifications also.
