I just got the new iPhone and sold my old iPhone. I want to erase all of the data, contacts, etc on the old iPhone before I send it out. I was told to do a "restore" within iTunes and that will bring the iPhone back to its original state and install the latest software. The problem I am having is the buyer of my iPhone doesn't want me to put the 2.0 update on the iPhone. How can I delete all the info on my iPhone without having to update to 2.0? Thanks for your input and time.
