Restore Iphone to factory settings without backup?
I have a 1st gen iphone that i just sold and need to send to the guy. I have created backups but not right out of the box. I was wondering how you reset it to factory specs? I thought i could just do the 2.0 update but at least one guy that has gotten the unofficial 2.0 said that he still has some of his stuff on the phone even after. Thanks in advance.
