Microsoft's retail stores have started taking pre-orders for the Nokia Lumia 900. Those willing to put down a $25 deposit can reserve either the black or cyan blue versions. Stores aren't saying when the device ships or how much it costs, although it may cost $100 on contract.
The Windows Phone is known to be shipping in March and may have a specific March 18 date. Only an AT&T-locked version is known to be coming so far, although a possible mid-year update could break the exclusive and take it to T-Mobile or other US carriers.
The Lumia 900 mostly upsizes the Lumia 800 with a 4.3-inch AMOLED screen that also improves the image quality. AT&T-native 4G LTE and a front camera are its other core additions. Nokia's choice of a 1.4GHz Snapdragon and 16GB of built-in storage remain intact.
