Listen up all you Palm Treo Pro hopefuls, your pre-order unit is now shipping with Palm’s on-line store showing in stock availability. The Windows Mobile phone matches up with specs from the initial launch and is considered Palm’s first true world 3G phone, with tri-band HSDPA covering service on AT&T and Rogers in North America as well as European, Japanese and Korean carriers. It also carries GPS mapping, Wi-Fi networking and a two-megapixel camera.

The handset ships only in its characteristic black and costs $549 as an unlocked phone for use with either AT&T or T-Mobile as well as foreign carriers, though 3G speeds are limited to AT&T for American customers.
