Sorry if this is a dumb question but I am a helpless female! I've got an iPhone 4 coming to replace a 3gs that I got rid of a while ago. I'd like to completely start afresh with this one as I think I'll be less likely to do something wrong if I try to do a "back up" (whatever that is). I would like to keep the apps that I had on the 3gs though, so can I start from scratch with the new one but somehow get my apps onto it ???
