I saw not to long ago about people selling their iphone on ebay and they ran into some problems with the buyer saying they just got an empty package and the seller was out his cash and the phone, at least that is what I read last. To my point I want to sell my iphone 4 and I have used ebay before but hearing all theses scams is starting to scare me. I was hoping to get some advice as to how to protect myself I have the phone wiped and am going to take the sim card out but I was thinking about locking the phone with a password not the simple lock. I will inform the person who buys the iphone that once they get the phone to email me to receive the password. Now I know this is not full proof as if they are smart or a quick Google search they can get round this but I just want to protect myself..... Any suggestions would be great.
