For those of you who are fortunate enough to own a shift, MoDaCo has released a Shift Pack that enables you to re-enable full Windows Mobile functions. The Shift, as you know, is a UMPC device created by HTC that runs both Vista and Windows Mobile with touchscreen. The caveat is that Windows Mobile on the Shift has been limited and only basic functions have been enabled.
The Shift Pack created by MoDaCo enables you to install CAB files to your device as well as synchronize the Windows Mobile and Vista sides through Windows Device Manager on Vista running on the Shift. It will also restore your Start menu on the Windows Mobile side.
