Anybody else have this problem? Yesterday evening and this morning my iPhone 4 and Mac Mini were all hinky dinky w/ finding each other and syncing. This morning, its like they can't see each other. Sync starts, spins for awhile, not contact is made on either side, and it just sorta stops. In the end I don't care as much. I had to choose between having my iPads wifi sync to the mini on the 5ghz 'n' network or my iPhone on the 2.4ghz 'g' network. So I put the Mac back on the 'n' and my iPads are still happy. I'll just plug my iPhone in like always. Just wondering if anybody else saw this yet?
