Let's face it: as Android users, we like options. One of the greatest things about this platform is the insane level of customization possible, especially if you don't mind getting your hands a little dirty. With some readily available tools (all of which are extremely free) and the proper knowledge, you can make your android phone do almost anything you could possibly want and make it look however you want.

That was quick - the Sprint's Epic 4G has already been rooted by the crew over at SDX-devs. In other words, now you can root that phone you don't have yet. It's a method requiring adb (Android Device Bridge) commands and thus desktop connectivity, but a one-click solution will probably emerge sooner rather than later. Note: it says EVO root, but the method works on this phone as well, don't let the filename fool you.
