The challenge series continues! Aaron switches over to the AT&T-branded Samsung Galaxy S III in the latest video installment of the 30-day challenge. The AT&T Galaxy S III has a 1.5 GHz dual-core Snapdragon S4 processor, and while it's incredibly close to the international version in speed, the quad-core Exynos edges it out ever-so-slightly. The battery life is a little bit less glamorous due to the 4G LTE connectivity, but the network speed boosts make it worth it. Stay tuned for the second half of the challenge!
