Three latest handsets–Palm’s Pre Plus, Pixi Plus and the Dell Aero smartphone–are set to debut on AT&T’s network.

The Palm handsets are previously accessible on Sprint and Verizon Wireless but AT&T will be the foremost to bid a Dell phone in the U.S.

The move is strangely to turn struggling cellphone creator Palm’s fortunes but it could proffer a goose to Dell’s entry into the smartphone business.

In January, AT&T said it will have five Android-based smartphones in its portfolio this year, and two gadgets running Palm’s webOS operating system. However the Pre and Pixi were hurled discriminative to Sprint in 2009, Palm unveiled a latest edition of the gadgets called the Pre Plus and Pixi Plus earlier this year.

Palm choked Wi-Fi support into the Pixi Plus and bumped up the memory and storage aptitude for the Pre.

Simultaneously, Dell made its sally into the smartphone industry last year with the Mini 3. The handset which runs Android operating system was obtainable only in China and Brazil.

Dell’s Mini 3 handset now has been renarded the Aero. And as seen on other Android phones, the gadget will trait a custom user interface, in this case developed by Dell.

AT&T hasn’t unveiled costing and rigorous availability gettable for the Aero. The Palm Pre Plus will cost $150 and the Palm Pixi Plus will retail for $50 after a two-year contract and a mail-in rebate.

On AT&T however, the Pre Plus and Pixi Plus will be missing a key trait. The two handsets won’t have the Mobile Hotspot app, available on Verizon’s editions, that permits the gadgets to become Wi-Fi hotspots themselves.
