I want an iPhone as much as the next guy, but AT&T creeps me out a little. They issued this press release last year, from which I will quote the important part:
The news media have carried reports alleging that AT&T is participating in an unlawful NSA terrorist surveillance program. Unfortunately, the law does not permit AT&T to respond to those allegations.
AT&T could tell us if they were spying on us, but then they would have to kill us. Multitouch doesn't sound all that great now, does it?
