Amazon has the AT&T Nokia Lumia 900 4G for $19.99, complete with free shipping for existing AT&T customers who re-up their contract. If you are adding a new line of service, either to an existing account or as new AT&T customer, the Lumia 900 can be yours for $49.99. That's a pretty great price for a phone that jumped to the #1 and #3 spots on Amazon's Best Sellers list upon its arrival. So if you missed Amazon's one penny pre-order period or Walmart's $49.99 sale, pop on over to Amazon.
If you are looking to pick up the Lumia 900 free of contract, you can also get it there for the full retail price of $499.99.
