If we had to name a device that's defined Sprint's smartphone lineup for the past year, we'd surely have to pick HTC's Evo 4G. The phone was an absolute blockbuster, brought Sprint WiMAX 4G to the masses, and remains popular a year after its release. In that vein, we're sad to see that the Evo 4G may have been End-of-Lifed. SprintFeed has the above screenshot from a tipster, pegging October as the EOL target for the Evo 4G.

The Evo 3D is its successor, but those dual 5-megapixel 3D cameras don't quite live up to the Evo 4G's single 8-megapixel shooter. More to the point, it hasn't been the gamechanger the original Evo was for Sprint, and the perennially down-on-its-luck network is always looking for another big winner in the Android lottery.

If you're thinking that there's always Samsung's Epic 4G slider to fall back on, think again. It's also set for an October EOL without an announced successor. Samsung's next-gen Android phone, the Galaxy S II, is still MIA on America's carriers, Sprint included. Thankfully, a Galaxy S II slider has been spotted with Verizon and AT&T support, so hopefully the Epic's EOL is a sign that the new slider may also don a Sprint logo in the coming months. Or perhaps it's a sign that times change and you're getting older by the minute. Get busy living, Evo owners.
