There's a good chance that by now you've figured out which plan you're going to get for your shiny new iPhone 3G. However, if there is some doubt in your mind that you're not going to get the right one, there is a handy little tool over at BillShrink.

It's pretty simple and straightforward. Just put in how much you're currently paying, then specify how many minutes, text and how much data you use. You can also put in your zip code to see how many bars to expect. Honestly, it doesn't really tell you much more than you probably already knew, it just puts it in a nice neat format.
