“...when you buy the new iPhone, you've also got to sign up to a two-year deal with AT&T, and AT&T has raised the price of its iPhone service plans.

Now Gizmodo has a new calculation incorporating other charges; it shows that the new iPhone costs $1,975 over 2 years, compared to the old phone's price tag of $1,815 over 2 years -- in other words, the new phone is $160 more than the old phone. ”
