I got a new refurb iphone 4 two weeks ago due to a bad home button on my old phone. Since then I've had the hardest time getting wifi sync with itunes to work again only for this phone. I can sync via the cable but as soon as I disconnect the icon for my phone disappears from itunes. If I try to manually force via the phone for wifi sync it says it will sync once it finds my imac. 1. Yes sync to wifi is checked 2. We have reinstalled itunes on Lion 3. two ipods and my wifes iphone are seen in the view but not my phone 4. Yes our AirPort Extreme has been restarted as well as the imac 5. We've restored my phone 101 times 6. We setup my phone as a new phone and still it disconnects Any other suggestions? I believe the fact my old phone was restored to my new phone has it looking for the unique identifier that would tell everyone it's on the wifi network (bonjour?) and I don't see how this unique ID could be deleted in favor of the new phone. Before you suggest items such as firewalls, restarting something else make note our two ipads and my wives phone all update via wifi just fine... try me!
