I'm trying to sync my phone through wi-fi, but I'm not getting the option on iTunes. I have the 4S, and the uTunes 10.5. I'm using Mac OS 10.5.8 and when I open iTunes, these are the only options I get:
As you can see in the screen shot I took, the "Synce with this iPhone over Wi-Fi" option is not available. I've updated iTunes and have a 4S phone, so I'm not sure what I'm missing and why this isn't displayed.
