Hello, I'm am planning on selling my iPhone 3GS 32 GB unlocked that is in great condition on ebay and I havent unlocked it yet and am running 4.0 currently so I am wondering that is it safe to assume that there will quickly be an unlock for the 4.0 software on my phone so that I can tell the buyer that I can ship it as soon as an unlock is available or should I just be safe and wait to put it up on ebay until there actually is an unlock available? Thanks for your opinions!
