According TUAW AT&T Announces Pricing for iPhone 4, but blogger TJ Luoma wasn’t happy when he found out that his iPhone upgrade date isn’t until sometime in February of 2011, so he called AT&T to find out how much it would cost him to upgrade to the iPhone 4. Here’s the scoop:

If you’re lucky enough to qualify for one of the “early upgrades” that get you out of the usual 18-month AT&T commitment period, then you pay just $199 for 16GB of joy and $299 for the 32GB model.

If your upgrade date is January 1, 2011 or after, early update pricing for the iPhone 4 will be US$399 for the 16GB model of $499 for the 32GB model.

Should you want a “no-commitment” contract, meaning that there’s no early termination fee for dropping the phone in less than two years, the price sneaks up another $200 to $599 for the 16GB model and $699 for the 32GB unit.

As with any major purchase, you should consider these pricing factors before you jump into purchasing a new iPhone. Remember; there will probably be a new model coming out in June of 2011, too.
