Hello everyone, and thanks in advance for your help. I just recently bought a used Ipad 1 32gb wifi only off of Amazon. I opened it up and it said it needed to be activated. I connected to my wireless network and it said it couldnt be activated at this time, so I connected it to Itunes to try and activate this way. It said I needed to have Itunes 10.5 and so I looked for the update and realized this 10.5 isnt even out yet! I sent the seller an email and he replied saying he was a developer and forgot he left ios 5 on this ipad. And sent me a file to install 10.5 beta 7. After installing itunes i tried connecting again, and it gave me the following error: "The software on the Ipad has expired and must be updated to a newer version." Is there any way to restore this ipad to ios 4 so that i can get this thing working? Do i have to wait for ios 5 to be released to gen public? Will it even work then or is this ipad worthless now? What are my options?!?
