Hi Guys, I've tried searching the internet for an answer but I can't find anything concrete. I ordered an iphone 4 from apple's website as an upgrade to my existing phone. This extended my contract, but I plan to just keep using my old phone. I have the new iphone 4 unopened in a box, and I'm selling it on ebay. This is where there's some conflict, do I open it and remove the sim? Without activation the sim shouldn't contain any information unique to my account should it? Sorry if this has been asked a lot. I did try searching your forum first, but couldn't find anything definitive. Thanks!
