It seems to work fine with the cable but if I do a wifi sync it shows that it finishes successfully but the content doesn't change on the phone. Then if I close iTunes and reopen the phone will pop in and then disappear. Then if I plug in the cable it will show it as a new device.
I'm doing another cloud restore and this time I'm not going to check the wifi box.
Worked fine in beta 4 manually. It would never sync overnight on it's own for me.
