Speaking at the "D: All Things Digital" conference yesterday, AT&T CEO Randall Stephenson said he expects its company to start selling the Palm Pre once Sprint's exclusive deal with the smartphone is up. While we've heard in the past that the device will be available at other carriers sometime next year, it wasn't clear exactly for how long the current agreement with Sprint would be in place.

Verizon is shedding some additional light on the matter today, however, revealing plans to start selling Palm's Pre in about six months. This is obviously good news for Palm, which will get to sell its device through the country's largest mobile operator, while Verizon gets more than enough time to see if the smartphone actually lives up to all the hype. The carrier also plans to have the new BlackBerry Storm available in that timeframe.

For now the only version we'll be seeing of the device is the Palm Pre for Sprint, which goes on sale June 6 through the carrier and a number of retailers across the country.
