My wife's iPhone automatically starts syncing when I plug it in to my iMac. My iPhone & IPad don't do this. I've looked at every setting on her phone that would be different than mine, but I must be missing something. What setting with her phone or iTunes will stop automatic syncing? Also, my phone goes through all the songs when I do sync, but hers doesn't do it even though the same songs are on hers (both phones sync properly, though). Anybody know what's going on or what the differences are? Both run the new iOS.
