I don't know if anyone has seen this, but it sounds great!!!!! Mobile Shell is my favorite interface replacement tool for Windows Mobile. It completely overhauls the interface and allows you to customize your home screens with widgets, notifications, and much more. We're hearing that Mobile Shell 5.0 will be shown at Mobile World Congress for WinMo, Android, and Symbian, offering "breathtaking 3D functionality" and "a huge number of widgets", which we'll be excited to see. What happened to version 4.0, you ask? For some reason, the number 4 is considered unlucky (you may recall that Microsoft released Windows 95 instead of "Windows 4").
