A friend of mine asked me a question, since I'm the local "Mac" expert, but I have neither an iPhone nor AT&T, so this isn't one I'd know about, and thought I'd ask here. My friend's mother is getting her an iPhone, and paying the AT&T bill for her, and she wants to know what information the bill payer has access to? For example, if you buy an iPhone for your kid (who is in college and lives in a different state), can you see their text messages, what apps they download, etc.? How much information about his or her iPhone activities can you access? (Please no "get a job" replies said friend does have a job and is with T-Mobile right now, but can't afford an iPhone's data plan, but obviously isn't going to say "no" to one.) Thanks!
