Telecom service provider AT&T has announced that it will carry Acer's Iconia Tab A501 4G tablet PC. Acer expects tablet PC shipments in 2011 to reach 5-7 million units, and aims to grab a 10% share of the global market, according to company chairman JT Wang.

The Iconia Tab A501 supports a 10.1-inch panel, Android 3.0 and Nvidia Tegra 2 dual-core processor. The device is scheduled to hit the market in the second quarter.

Verizon Wireless reportedly is interested in Acer's other tablet PC, the Iconia Tab A500, according to industry sources.
