I have a 16GB white Iphone 3GS and I dropped it and broke the screen. I am selling it on ebay. What is the best way to clear off the data that is on it? I've done the restore thru Itunes and then did the erase data on the phone after the restore. Is there more that needs to be done? When the new person gets my phone will it still be connected to my phone number? my name still attached to the serial number? Thanks for the help.
