Wireless provider AT&T on Tuesday announced it would soon begin selling 3G-connected netbooks in its stores nationwide and add more offerings to the lineup. Buyers will be able to choose from netbooks from Acer, Dell and Lenovo from all 2,200 AT&T retail stores in the US sometime this summer. Each will have embedded Wi-Fi along with internal 3G access on the carrier's HSPA network.

AT&T began offering netbooks in April in just two markets, Atlanta and Philadelphia, as part of a trial run, subsidized like cellphones when purchased on a data service contract. It offered netbooks from Acer, Dell and LG, with subsidized prices ranging from $50 to $250 on a two-year contract.

The new additions to the lineup, their prices and dates of availability will be announced later, AT&T said.
