I sold an iPhone 4 on eBay recently for $160 after light use. On my listing I posted used condition and "no returns accepted". Comes to find out that the buyer tries to get it activated and is told it was a stolen phone, which I had no idea of since it was given to me as a gift.

Can I restore my iPhone from iTunes after jailbreaking?

I have a jailbroken iPhone 4s running ios 5.1.1. I want to upgrade to ios 6.1 and jailbreak right after.
I have backed up my iPhone right now, with cydia, installous and all my tweaks still on the phone.

My question is, after upgrading to ios 6.1 can I restore my phone to the latest backup in iTunes?

My process would be this:
-restore iphone via iTunes
-download and update iPhone to ios 6.1
-jailbreak ios 6.1
-restore in iTunes via the backup I mentioned from earlier today.

Would restoring via my backup create a problem with the phone?

Is there a better proces than this?

ITunes won't let me sync the music from my iPhone to my laptop?

So when I click to sync the music from my phone to the iTunes on my laptop, it says this:
The iphone "Gabys Iphone" is synced with another iTunes library. Do you want to erase this iPhone and sync with this iTunes library?
An iPhone can be synced only with one iTunes libraby at a time. Erasing and syncing replaces the contents of this iPhone with contents of this iTunes library.

I don't really understand what they are asking me. Can someone explain? Thank you.

P.S The only other place i synced my iPhone to was on my parents old Windows 8 computer, which they returned to the store because they didn't like it.

Can AT&T lock a stolen iPhone?

I plan on selling some iPhones on ebay that I just got factory unlocked. They are iPhone 4 GMS. I have heard a lot about sellers getting scammed on ebay, and ebay usually sides with the buyer. Can I have an unlocked iPhone reported stolen if it has no account associated with it? The service will be transferred to a new phone first. I was hoping that if someone tries to scam me out of a phone I can at least have it disabled by AT&T. Can they do that?

Can I get my stuff back on my iPhone 4?

My phone randomly shut off so I had to put it in DFU mode and restore it. I did back it up, but that was when I got it a couple months ago. Since then, I've accumulated dozens of pictures, contacts and apps. Now my iPhone is how it was a couple months ago. Is there anyway to get it to be like it was before it shut off today? Shouldn't it be saved with my Apple ID or something?
