Sprint announced Nov. 15 as the first day of nationwide availability for Palm Pixi. The device will sell for $99.99 after rebates with a two-year contract.

Besides Sprint stores and online, the device will be distributed at Best Buy, RadioShack and select Wal-Mart stores.

The phone has a multi-touch screen and full qwerty keyboard. Like the Palm Pre that launched in June, the Pixi runs the Palm webOS platform.

Application developers will get a chance to learn more about Palm webOS at Sprint’s ninth annual developer conference beginning today in Santa Clara, Calif. The Sprint Open Developer Conference will feature information through speaker sessions and coding camps on developing applications for a range of platforms, including webOS.

Palm is a premier sponsor of the conference, and Ben Galbraith and Dion Almaer, directors of Developer Relations for Palm, are giving a keynote address in addition to running several breakout sessions and coding camps focusing on the webOS platform.
