My current favorite Nokia device is the Nokia E71 (see my review) and I think it is the BEST S60 device I have every owned. It is sleek, solid, and a superb performer with only the camera serving as the weak point of the device. The Boy Genius Report has information that the E71x may finally be coming to the United States through a wireless carrier with a 24 March rumored launch on AT&T for US$199.99 after rebate and contract.
This model also will be all black in color, rather than the black and silver North American model I own. The fully SIM unlocked model runs about $350 so I don't know if there is much benefit in actually buying this one from AT&T. A couple of key things I will be looking for from those who buy this device is the camera quality and what version of the operating system is running. Hopefully, AT&T doesn't pull something like they did with the E61 and remove WiFi or some other function from the device.
