Update: Palm expects that the update will be free. Their rep told is: "However if carriers have requested other items to be included in the same update, there might be a small fee. Timing will be dependent on carrier certification schedules and I can't say for certainty when the update for the unlocked version will come out and if it will be first."
From the Press Release:
Palm today announced that an update to the Windows Mobile 6 Professional operating system will be available for Treo 750 smartphone customers around the world.
The Treo 750 is available from carriers in the United States, Europe and Asia and remains a key part of Palm's international expansion strategy to make Treo smartphones available to more customers. For AT&T customers, the update also will facilitate High-speed Downlink Packet Access (HSDPA) capability allowing faster data-download speeds on 3G/UMTS/HSDPA networks.
"Palm continues to work closely with Microsoft to maximize the benefits of Windows Mobile and to deliver the best mobile experience to Treo customers," said Joe Fabris, director of wireless solutions at Palm, Inc. "Our hallmark Palm experience combined with the benefits of Windows Mobile 6 on the Treo 750 will continue to deliver a great productivity tool for businesses across the country and around the world."
The Treo 750 is a five-band world phone that combines a great phone with email, messaging, web browsing and organization software. Because the Treo 750 is based on GSM radio technology that is widely available around the world, it is a natural fit for multinational businesses or employees who travel internationally. The flexibility of the Treo 750 combined with Windows Mobile 6 will help the Treo 750 continue to build on its momentum in the business market.
Windows Mobile 6 paired with Exchange Server 2007 will deliver email enhancements such as HTML-formatted email messages, the ability to set an out-of-office message remotely, and live links to Microsoft SharePoint documents. Also, the Treo's color touch screen makes line-of-business applications easier than ever and allows users to take full advantage of new mobile versions of Microsoft Office Outlook, Office Word, Office Excel and Office PowerPoint. Microsoft's Direct Push Technology continues to be available out of the box, giving Exchange users fast, automatic wireless updates of their email, calendar items, contacts and tasks without additional third-party software or fees.
"Windows Mobile delivers to the small screen a rich and familiar experience that meets people's work and life needs while on the goall with a single device," said Chris Hill, group product manager, Microsoft Corp. "We are excited to work closely with Palm to offer a Windows Mobile 6 update to existing Treo 750 users so that they can take advantage of new and enhanced productivity and advanced communication capabilities."
