Did we get an update or something. I read that in order for iPhone 4s to wireless sync with iTunes, phone needed to be plugged into charger and connected to wifi. Well this a.m, I was able to sync with iTunes wireless without charger. I'm moving some PDFs to iBooks and fired up iTunes, it found my Phone, so I synced and boom. I was trying to avoid connecting to charger because I still had 60% and didn't want to reset my usage history. I'm trying to document for a user here that's having battery issues. But am I missing something on the need for charger. In fact, in the "iTunes Wi-Fi Sync" menu the "Sync Now" button is grayed out until the wall charger was connected. And it states, "Automatically sync with iTunes on your computer when your iPhone is plugged in to power and connected to Wi-Fi" I'm not complaining, its definitely easier to sync without need for charger. I mean if I'm gonna get charger our and plug in, why not just plug in to computer and then sync is faster. I always thought that was odd for the need of power, but after thinking a bit......i guess it would be bad if the phone died due to low battery right in middle of sync. So I never complained. I definitely like this better, just wondering when and if it changed or am I the only one getting this "feature" Oh and BTW, I screenshot 3 or 4 screens in middle of sync for those who are skeptical It shows sync in top and you can see its not plugged in. Also a usage screen shot of battery life so we can see it wasn't plugged in at anytime because the usage wasn't reset.
