My cell service is with Verizon and I'm in no big hurry to switch. Cingular/AT&T customers in my area do nothing but b1tch about dropped calls, static, being unable to find a connection, etc. That alone deters me from picking up an iPhone at the moment. Plus, they haven't announced the service plans for the iPhone yet, and I have a feeling they are going to be brutally expensive. The iPhone is an amazing device; so much more than a phone or even a Blackberry (it's a full blown, fully functional computer). But the exclusive pairing with AT&T is enough to make me stay away for the time being until the bugs are worked out, the Cingular service in my area improves and the service plans aren't horrendously steep. The device is going to be a smash hit without my money, anyway, so there will be more iterations of the device to come. It pains me to say as a die-hard Mac Zealot, but I'm going to wait awhile.
