A couple of good blog posts explaining the new AT&T data plans for iPhone.

It will be a money saver for 98% of users. Personally, although I have never gone over 2GB usage in a single month (1.4GB was the closest) I plan to hold on to the Unlimited plan for a little longer. I can transfer it to my new iPhone that I will be getting later this month.

The first link are nuts and bolts answers. The second is more opinion based, from one of the (if not the) most respected tech blogger on the Internet.

1. I'm debating on getting the unlimited just to lock myself in.

But as an at&t employee, it's the 50% emp discount promised to us that intrigues me. The internal company announcement doesn't say for iPad, where it's prominent for the phone plans.

This limited GB announcement comes 2 days after I buy a car stereo that streams Pandora from my iPhone!:grr:

2. Pandora is always interesting for 2 or three songs, but then it goes off on an annoying tangent.

I have Wunderradio on my iPhone. 36,000 radio stations. I always have something to listen to wherever I go.
