Palm has debuted the latest addition to its Treo line of smartphones, the Treo Pro. The announcement comes less than a week after photos and details about the new handset were leaked on the Web. Aimed at business users, the mobile device will be available in Europe in September through carriers Vodafone and O2, as well as in an unlocked configuration. It will also be offered by Australian provider Telestra, which will offer the Treo Pro free with a contract. In the U.S., the smartphone, remains carrier-less and is available only in an unlocked, unsubsidized version.
