I just read over at Palm Addicts that O2 has announced the launch of the Palm Treo 500 that was previously only available as the 500v on Vodafone.

Palm Europe Ltd. and O2 today launched the Palm® Treo™ 500 smartphone, which combines multiple forms of communication with high-speed 3G/UMTS mobile Internet access.(1) Aimed at large- and small-business users, the Treo 500 smartphone is available across O2’s top 100 stores as well as through its direct sales teams and online shop. Running on the Windows Mobile® 6 Standard platform, the device offers business users viewing and editing capabilities for Microsoft Word and Excel documents, a full keyboard for quick and easy messaging, a large full-colour screen and a comprehensive multimessaging functionality covering email, IM, SMS, phone, and contact and calendar capabilities -- all in a compact form factor.(1) The device, which comes in charcoal grey, is available free from O2 on select Pay Monthly tariffs, dependent on the tariff taken.

The Palm Treo 500, which looks very much like the Palm Centro in Black, is aimed at business users.

“Business users today are looking for compact devices that offer not only business functionality, such as email and access to documents, but also multimessaging capabilities and high-speed Internet access. The Treo 500 smartphone provides everything you need to manage your work and personal lives whilst on the go,” said Roy Bedlow, vice president, Palm EMEA.

I'd love to get my hands on a Treo 500. Doesn't look like we'll be getting the device over here in the states though.
