Dell today announced that U.S.-based AT&T will become the next mobile operator to offer a smart phone from the Mini 3 Android-based lineup.

Over the past two months, Dell has established smart phone arrangements with mobile operators including the world?s largest, China Mobile, Claro in Brazil, and now AT&T.

The Android-based platform gives the Mini 3 optimal power, flexibility and customization opportunities for both users and operators. With AT&T?s largest Wi-Fi hotspot network, and fastest 3G network, Dell and AT&T will provide today?s social media mavens with the ability to simultaneously Tweet friends, post Facebook updates, share pictures and browse the Web.

Dell has existing arrangements with other global telecom providers, including Vodafone in Europe, Australia and New Zealand; AT&T in the United States; M1 and Starhub in Singapore; Maxis in Malaysia; China Mobile in China; and Claro in Brazil ? each creating more opportunities to meet the needs of the connected lifestyle.

Details about Dell?s Mini 3 will be announced by AT&T closer to device availability expected during the first half of 2010, the company said.
