I'm glad it's resolved, and iPhone wasn't to blame, but I was most impressed that the network experts figured a tiny iPhone could send 10 megabits of small packets per second, wirelessly, doing all necessary processing, while simultaneously playing video and audio, and communicating with the AT&T network, on a battery that lasts for a workday under full load. That is really incredible!

What makes the iPhone remarkable is the clarity of its audio (on a GSM network!) and its intuitive and pleasing user interface. (BTW, (!,?) = Wow! Really?
