The Galaxy S4 line of phones is quickly growing, and the next to join Samsung's Galaxy party is the S4 Active. Available exclusively for AT&T and starting at $199 on contract, the Active is nearly identical to the original S4 in terms of performance. However, this thicker and heavier version can withstand submersion in up to 1 meter (3 feet) of water for up to 30 minutes. The S4's water resistance does come with some caveats, but the Active lives up to its name. With AT&T's early upgrade plan Next, you can get the Active for 20 monthly payments of $26.
