Hi my iPhone (3GS) and Timemaster Central broke up how can get them together again. It worked perfectly last night yet today they can't/won't see each other. I have tried the repair on "Bonjour" as suggestedbut nothing. I am on Windows 7. Any suggestions

Perhaps you can try resetting all your Wi-Fi devices on the network. Wi-Fi routers, iPhone, etc. Sometimes the iPhone takes at least 30 seconds to re-attach to the Wi-Fi network. Also make sure that you are using Time Master Central 2.1.
