I watched a news story today that was talking about the satellite connectivity the new iPhones are going to have, and it's going to be a subscription service. I don't think they mentioned prices, but I guess you'll have the ability to pay for a cell phone and sat phone all in one. The sat phone will only work when you have zero cell signal, and it will be limited to texts and calls only from what I understood, so you'll mostly be paying for a safety feature.
Not quite what I was expecting, but interesting nonetheless.
