For the longest time SPB Mobile Shell was easily the best choice to customize the look and feel of your touchscreen Windows Mobile device. Our review of the most recent version of Mobile Shell (version 3.5) touted SPB’s penchant for putting so much functionality at your fingertips.

Somewhat lost in the shuffle of Microsoft’s big Windows Phone Seven Series announcement at Mobile World Congress, SPB announced version 5.0 of SPB Mobile Shell. Mobile Shell 5.0 introduces a number of new features such as a 3D engine which allows for a number of 3 dimensional graphical effects  and 3d widgets. Improved support for social networks such as Facebook and Twitter will allow for status updates as well as contact and photo synchronization. One innovative feature that SPB is introducing is their Natural Interaction Engine which will provide support for technologies for Multitouch and G-sensors.

SPB has made a significant investment in the developer/hardware manufacturer segments with Mobile Shell 5.0. SPB UI Builder 2.0 is a set of tools that allow for customization of Mobile Shell and includes access to a number of APIs and includes a skin builder and plugins for integration for industry tools such as 3DMAX and Microsoft Expression Blend.

We have hands-on video coming. Stay tuned, folks.
