The carrier claims to be the first in the U.S. to offer Samsung's Galaxy series, starting with the Galaxy S, dubbed the AT&T Captivate at the time. In terms of the Galaxy S4, though, Sprint, Verizon, T-Mobile, and regional carriers have all committed to carrying it.
Of the other Big Four carriers, T-Mobile recently revealed that it plans to offer the Galaxy S4 beginning May 1, but it was not clear if that meant pre-orders or an actual retail appearance in T-Mobile stores. AT&T's announcement similarly is light on details, not saying when the device will hit retail.
The Galaxy S4 features a 4.99-inch, 1080p Super AMOLED display, 13-megapixel rear-facing camera, and Android 4.2.2 with Samsung's TouchWiz UI skin and features.
Although AT&T did not detail storage capacity details, past history would point to the smartphone carrying 16GB of internal storage. It's also unclear what processor the AT&T version will ship with, though it's expected that U.S. users will see their devices bereft of the Samsung Exynos 5 Octa 1.6Ghz processor and instead ship with a Qualcomm quad-core Snapdragon 600 CPU clocked at 1.9GHz.
Last year's Samsung Galaxy S III turned out to be one of the best selling smartphones of the year, and we have no doubt -- despite Samsung switching from Roman numbers to Arabic -- that the Galaxy S4 will repeat that feat this year.
