If you've been looking to jump ship from the carrier juggernauts and get in on Sprint's promised "truly unlimited data", may we suggest now might be a good time to do so? From now until March 26th, all of Sprint's 4G phones (read: Sprint's best phones) are available for a penny with a new activation. Sorry upgraders.
Update 4/20/12: All Sprint Android phones are free again thanks to the Sprint Through Spring promotion... well, at least until the Galaxy Nexus shows up. Remember, offer ends April 30th and midnight PDT.
Amazon is even waiving the activation fee, so you'll be hard pressed to find a better deal on a shiny new Epic 4G Touch right now.
