Unless my plane has less than 6 seats in it, I'm pretty confident I'm going to have service with my phone. The only exception to that I've found in Arizona are the casinos. They seem to have some serious cell service zapping technology to keep you focused on pulling that levers. Though I can still get a bar or two here and there.
And yea, there are some pretty cool phones. I don't have one though. I have a phone that's positively archaic - almost 2 years old. SO old. One day I'll get a fancy one, but they don't have the kind of phones I really like most, so I might have to wait another year or so. Amazing. Most phones are so disposable now days mine will be an antique by then.
