The other shoe has dropped and Apple has announced the rate plans for iPhone. The iPhone plans are metioned in the activation and sync video and in an Apple press release and are relatively affordable.
The surprise is that all three plans include unlimited data, visual voicemail and 200 SMS text messages. I would have preferred to have unlimited SMS included in that price, but that's me. 1500 SMS text messages will cost an extra US$10 per month and unlimited SMS will cost an extra US$20 per month.
