I follow Chris Coyier’s Blog and just read his post, Bullhonkey on AT&T.

I just purchased an iPhone and was thinking about upgrading to the new iPhone 3G s but it turns out that to do so I’ll have to pay MORE than someone who is a new sign up.  Where is the customer loyalty?!?

For non-qualified customers, including existing AT&T customers who want to upgrade from another phone or replace an iPhone 3G, the price with a new two-year agreement is $499 (8GB), $599 (16GB), or $699 (32GB).
