Hi, i have iPad 2. I just Plugged my iPad to my Windows OS with the updated latest iTunes. I just Tapped the Check box of “Sync iPad over WiFi” in the Summary Tab of iTunes. Now i just Plugged out my iPad from iTunes which was connected via USB. I just checked my iPad for Sync over WiFi but the Button to Tap on “iTunes WiFI Sync” is Grey and not highlighted. So i can’t Sync my iPad to iTunes via WiFi Connections. Kindly check out & do the needful steps asap.
