We already know that the Galaxy S III is coming to five major carriers in the U.S., and T-Mobile just dropped all of its plans into the public lap. Here's the skinny.

Aesthetically, this device not only looks identical to the international version, but also like what we've seen from the other U.S carriers thus far. Internally, T-Mo's GSIII will also match the other U.S. variants of the device: 4.8" 720p Super AMOLED HD display, 1.5GHz dual-core Snapdragon S4, 2GB of RAM (!!), and Android 4.0.

While T-Mobile has yet to release pricing information, we know that it will carry both the Metallic Blue and Ceramic White variants in both 16GB and 32GB models, all of which will be available beginning on June 21st. If, for some crazy reason, you think you may forget what day it's supposed to land, you can hit up T-Mo's GSIII landing page to sign up for updates.

Who's going to be in line?
