Hey all, my iphone was showing up to wireless sync, when today it disappeared, and I can't get it back. I have done the manual sync, and then checked the sync over wi-fi box box already. It will show up if I manually sync it using the cable, but after I disconnect, it does not show as being connected through wi-fi. The wi-fi sync box is checked in the iphone summary window, and both iphone & imac are on the same network. In my iphone General Settings under the Itunes Wi-Fi Sync option, it says "Sync will resume when Imac is available".

What am I missing?
