We heard yesterday that AT&T would receive the Galaxy S4 first, on April 26, but it appears that the Staples document was off by a few days. It looks like the official pre-order availability and pricing for the Galaxy S4 is now here, and on AT&T's website.
The pricing is $199 on a two-year contract for the 16GB Galaxy S4 in either white or black, and if you want it outright, it's going to set you back $639. If you want it on a one-year contract, then that price comes down to $449. You can pre-order right now, here, if you want it with the estimated May 3 arrival date. You know you want to.
