Man, I’m pretty steamed about the just-revealed details of the iPhone 3G price plan — and if you’re an existing AT&T customer, you should be too. After all the fuss about the $199 iPhone, it turns that those of us already on AT&T plans are going to have to pay twice as much — namely, the existing iPhone price of $399.

Not surprisingly, I’m less-than-thrilled about this news. It’s starting to feel like everything after the announcement of the iPhone 3G at WWDC has been a string of “Wait, but there’s a catch …” First, AT&T said it’s increasing the price of iPhone’s data plan by $10 a month. Next, MG Siegler noticed the real ripoff: You’ll need to pay extra for text messaging.

Still, those announcements fell under the heading of “annoying but fair.” Basically, they seemed like AT&T’s way to recoup its iPhone subsidy by charging its customers extra rates. This news, however, means that people like me — AT&T customers who haven’t bought an iPhone yet — get the worst of both worlds; we lose out on the discount, and we get to pay the increased rates. It’s like I’ll be subsidizing AT&T’s efforts to bring customers over from other carriers. Um, thanks?

So you’re probably thinking, “If you don’t like it, why are you buying an iPhone?” Good point. In fact, I’m so peeved about this, that I’m going to boycott the iPhone. For a day.

It’ll hurt, but I’m totally going hold off on my purchase until July 12. Take that, AT&T!

Update: As several commenters pointed out, I should have mentioned that if you’re eligible for a phone upgrade, you can still pay the lower iPhone prices. Sadly, I’m not eligible for such an upgrade, so my boycott plans proceed apace.
