Hello. My iPhone is running iOS5 and iTunes is version 10.5. Both my MBP and iPhone are connected to the same network and connected via USB. However, the option to "sync with this iphone over wi-fi" doesn't show up on in iTunes under my Summary. Any one have any idea why? I already synced once or twice using USB and I've restarted both my computer and iPhone. Any help would be appreciated. Please and thank you.
