Android devices have finally come to AT&T. The carrier, which has benefited a great deal from its exclusive deal to carry Apple's iPhone, is the last major network to offer a phone loaded with Google's mobile operating system.

Now it plans to enter with a splash, by offering customers five devices, made by HTC, Dell, and Motorola, all within the first half of this year. Dell's Mini 3 will reportedly be the first device for AT&T's network to hit the market.

Some are speculating that AT&T's sudden big push into Android is inspired by the impending end of its iPhone deal.

The announcement was one of a series that AT&T made this week at the company's developer conference in Las Vegas, which coincides with CES. The carrier also announced that it will improve the speed of its 3G network.
