iTunes to iPhone "Unknown error 0xE800007F"

Same problem here, on two phones.

Wife: iPhone 4; iOS 5; WiFi sync enabled; not plugged in to wall

Me: iPhone 4S; iOS 5; WiFi sync enabled; not plugged in to wall

Internet: 20+ Mb/s Time Warner Cable routed thround 5th gen Airport Extreme.

Fix it.

I Get the same thing 2 iphone 4's and it seems intermittent, sometimes it syncs. if i power cycle my router and computer and iphones it seems to work ok for a short time, then I get the unknown error or cannot find the iphone etc.

I hope someone has a solution for this soon, i'm not smart enough to figure out what the problem is.

Thank you very much for that.

So, evidently, even people not in the USA, and who haven't even heard of uverse, are having these problems with their iPhone ;-)

Thanks for that imanog, I have been looking for a page that would explain some steps, I do have Windows. So I'm hoping this Helps.

Much Appreciated, I'm gonna give that a try right now.

You are kidding, there's enough problems here and elsewhere to work out there's a bug in iTunes that is causing this error. Shouldn't be up to the end user to self diagnose this problem Apple should fix this and then patch iTunes. Anyway that tech article says nothing about error 7F.

also as a result of this problem the sync failed on my iPad, I ended up having to enter my user names and passwords for everything i login to i.e. facebook, twitter, dropbox etc. how annoying.😠

You're right NickRno77, Apple should fix but, meanwhile, but it has solved the problem for me, or at least it appears to have done.

Same for me...inconsistent error on 2 separate iPhone 4s and 2 separate iPad 2s. Sometimes it syncs, sometimes this error. Latest iTunes, Win 7 64bit.

That's great wilf21 , can you remember exactly what fixed the error.

Thanks

Same issue on latest iTunes on XP with both my 3GS and my iPad 1

"That's great wilf21 , can you remember exactly what fixed the error."

Yes, following the instructions in the email reference earlier (and remember this is for a PC, not a Mac), I disconnected any Apple devices from my PC, closed down iTunes, went to C:\ProgramData\Apple and deleted the Lockdown directory. I then (not part of the instruction, but I did it anyway) restarted the computer.

Haven't had the problem since.

I can confirm that this had just worked for me too. Problem fixed... at least for the first sync.
