MyWi 4.0 is a complete rewrite due to complexities involved with iOS 4 on Apple's behalf.   We hope you understand that our efforts to create MyWi 4.0 were many more times than that of the original.   Other Intelliborn products such as IntelliScreen, Elert, My3G, IntelliDial and Tlert have been released as free updates given the more simplistic nature of the work required to make them function on 4.0.
