I am running Windows Mobile 6.0 on an HTC TyTn II and have never successfully managed to complete an update to the operating system. The error message always says "Connection to update server was not available. Check your data connections settings and ensure the device date and time are correct". I am connected to the internet via a wi-fi router, and have no problem using other internet dependent programs including Internet Explorer. It seems that I'm not the only person with this problem, but have yet to find an answer that either solves, or at least explains the problem. Thanks.
