iTunes to iPhone "Unknown error 0xE800007F"

I have Wi-Fi Sync active and it works great unplugged from power -- but when I plug my phone into power and it starts syncing, iTunes says the following:


"iTunes could not connect to this iPhone because an unknown error occurred (0xE800007F)."


Searching gives me zilch. Anyone have an ideas? Everything is running the latest verison of iOS, etc., etc...

I have a similar issue. I have an iPhone 4 and an iPad 1, both are configured to WiFi sync and do so when connected to power. The issue I have is that when iTunes is running in background on my laptop, for some unknown reason, randomly the same message ocurrs. So, to clarify, I'm not even attempting to sync and the iPad and iPhone are *NOT* connected to power.

Yup. The issue seems to be for me exactly above. As soon as iTunes detects my iPhone I get this message. Tested by leaving wifi range. When connected to to my Wifi network again the error message appears.


Similar also to others at times when I try to sync, I get a message saying that it isn't possible because my home computer is not in range. So at times itunes and the iphone 4 can't see each other.


If there's one thing Apple are not good at, it's getting wifi to work properly. Even my macbook air can't find a wifi network that every other machine in the house can find automagically.

Something like that is also happening to me. I have the iPhone 4 with ios5 and iTunes 10 in my PC and in my case even if iTunes is not running, it will from time to time launch itself and after about 30 seconds the same error pups up.

I also sense a delay and even a fail to respond to my commands (the iTunes page) when i click in several areas of the page.

I hope Apple comes up with a fix soon because it is very annoying.
