I have not been able to wirelessly sync to my win7 laptop since Oct 19th according to what it says. My husband was at the laptop and said an update was downloading for iTunes. After the update I looked and still grayed out. I than had him open iTunes and suddenly I was able to sync wirelessly. Seems to defeat the purpose having to go to laptop, open iTunes and back to iPad to sync. might as well plug it in with USB... hope they fix this soon.
