Dell said that it is launching its Android-based Mini 3 line-up of smartphones in the US with AT&T as the carrier.

Dell said that the arrangement with AT&T is part of its focus on developing smart mobile products and services through relationships with operators. Dell has existing arrangements with other telecom providers including Vodafone in Europe, Australia and New Zealand; AT&T in the US; M1 and Starhub in Singapore; Maxis in Malaysia; China Mobile in China; and Claro in Brazil.

With AT&T’s Wi-Fi hotspot network and 3G network, the companies will provide social media users with the ability to simultaneously tweet friends, post facebook updates, share pictures and browse the web, Dell said.

Ron Garriques, president of Dell Communication Solutions, said: “Smart phones are an extension of Dell’s strategy to develop intelligent and more mobile products that meet the needs of operators and customers. The Mini 3 is a result of listening to customers and creating products that allow people to do the things they want, whenever and wherever they want to do them.”

David Christopher, chief marketing officer of mobility and consumer markets at AT&T, said: “As the leader in smart phones, AT&T makes a great match with Dell to introduce the next Mini 3. We offer our customers what no one else can, the nation’s fastest 3G network, the nation’s largest Wi-Fi network and now, Dell’s first smart phone in the US.”

The Dell Mini 3 is expected to be available during the first half of 2010.
