I put my 16 gig 3GS on ebay last night in anticipation of getting my iPhone 4 on Thursday. Started the auction at $99 and threw out a $499 buy it now (I included my incase slider, original box and equipment, and also one year of my squaretrade warranty). Within 30 minutes of it being up someone did "Buy it now". Needless to say I was pumped. I checked this persons profile out this morning and it says "No longer a registered user". Now, obviously I wouldn't sent the phone to them until their payment is in my paypal account but is this some type of scam?? I sent them a message and if I don't hear back from them by the end of the day today I am thinking of just relisting it. Has this happened to anybody else before?
