Just came back from the O2 store with my new iPhone after owning a 3G. Plugged into iTunes and activated (although, still waiting for activation to happen after an hour). When plugged into iTunes I couldn't restore from 3G backup because the iPhone was boxed with 4.0 and the 3G had 4.1, so had to do a clean satup. Got a alert message from iTunes saying I could restore to a backup after I had upgraded to 4.1, so I did. Upgrade the iPhone 4 to 4.1 and restored to the latest 3G backup. All fine, except I don't have any of my apps i'd purchased, only the standard ones. How can I get them back?
