Palm today corrected its premature launch yesterday with a more formal introduction of the Treo Pro, including its launch information. The Windows Mobile 6.1 smartphone is the first major redesign of GSM-based Treos and sports a normal headphone jack, a Wi-Fi toggle button, and a hardware ringer switch like the iPhone. It also becomes the first Treo to support tri-band HSDPA for 3G access on AT&T and similar carriers and uses true GPS for navigation.The Treo Pro's launch starts in September, when the phone will ship through both O2 and Vodafone in Europe as well as Telstra in Australia; pricing will vary by the carrier but offers the phone for free with high-end plans and peaks at €399 for basic plans. An American launch is due in the fall and will start out with an unlocked, carrier-independent version at $549 that can be used for 3G on AT&T as well as calls and 2G data for both AT&T and T-Mobile.
Plans for a locked but discounted AT&T version haven't been announced.
