Q: I’ve recently upgraded to an iPhone 4 and am looking to convert my old iPhone 3G profile for my wife’s use. We both use the same iTunes library and account, so I’m wondering if there’s anything I need to do like reformat it or if I can simply change the profile to say her name instead of mine? The other issue is that it will want to update to the latest OS and I’m not sure how to prevent it from doing that, as I know…
