5.2.1622 on HTC Wing). In WM 6.1, the CE version is 5.2.* with a five-digit build number (e.g. 5.2.19216 on Palm Treo 800w). Windows Mobile 6.5 Windows Mobile 6.5 is a stopgap update to Windows Mobile 6.1, based on the Windows CE 5.x kernel, intended to bridge the gap between version 6.1 and the then yet-to-be released Windows Mobile 7 (Later canceled in favor of Windows Phone 7), that arrived in 2010. It was never part of Microsoft's mobile phone roadmap, and has been described by its chief executive, Steve Ballmer, as "not the full release Microsoft wanted" until the multi-touch-enabled Windows Mobile 7 (now replaced by Windows Phone) arrived in 2010. Ballmer also indicated that the company "screwed up with Windows Mobile", he lamented that Windows Mobile 7 was not yet available and that the Windows Mobile team needed to try to recoup losses. Microsoft unveiled this version at the 2009 Mobile World Congress in February, and several devices were supplied with it.

This update includes some significant new added features, such as a revamped GUI, a new Today screen resembling that of Microsoft's Zune player with vertically scrollable labels (called 'Titanium') in terms of functionality with a styling similar to that of Windows 7. WM 6.5 also includes the new Internet Explorer Mobile 6 browser, with improved interface. Along with Windows Mobile 6.5, Microsoft announced several cloud computing services codenamed "SkyBox", "SkyLine", "SkyMarket". "SkyBox" has been confirmed as My Phone, while "SkyMarket" has been confirmed as Windows Marketplace for Mobile. This version was designed mainly for easier finger usage. Some reviewers have noted interface inconsistencies, with some applications having small buttons making them harder to operate using only a finger. Whilst this version of Windows Mobile does not natively support capacitive screens, mobile manufacturers have been able to use them on their devices. In the months following this release, development shifted from Windows Mobile to its successor Windows Phone. As such no major upgrades were planned or released, although three minor updates; 6.5.1, 6.5.3 and 6.5.5; were made to satisfy consumers during the transition period. 6.5.1 brings larger user interface elements, including icon based soft buttons (rather than text based),
