  • What version of IOS is this iPhone? I'm selling this on eBay: http://cgi.ebay.com/...00wt_1284… And I got asked that question. I bought it from another person off eBay, and immediately re-sold it after realizing it couldn't be activated with my carrier. So I don't know much about it. Is the answer to that question in the product details, or is it something I should ask the person I bought it from?

  • Restore back to iOS 6 to download Official version of iOS 7? I currently have iOS 7 Beta 2 running on my iPhone 5. My question is that when the official version of iOS 7 comes out in the fall, will I have to restore my iPhone back to iOS 6.1.4 in order to install the official version of iOS 7?
