Just wondering, I've only ever had one iphone. I'm in the process of reseting my 3g to recycle it with o2 tomorrow as i'm going on holiday at the end of the week so can be without a phone till when i get back when apple will (hopefully) of delivered it and it'll be waiting for me. What is the best way of setting it up so that i loose none of my games, texts and settings and stuff? Can i restore the iphone4 from backup even thought the iphone 4 should come with ios4 preinstalled? I can see i'm going to loose everything here aren't i?!
Back up your iPhone with iTunes, then when you get your iPhone 4, restore from that back up
