I currently own a Samsung A707 (or the Sync). Like just about every phone, it has a profiles section in the settings menu. I can change to a driving profile, silent, etc. One of the ones I enjoy is the Airplane profile. This shuts off the cellular antenna but leaves the rest of the phone's functionality intact. My question is, does the current iPhone have some sort of similar functionality? If I wanted to shut off the cellular and/or wifi antenna, would I be able to? Thanks!
