See that package above? That phone-and-case combo could find a home in your hand, thanks to Otterbox. The company, which is well known for its durable cases, has an AT&T-branded Samsung Galaxy S 4 to hand out to one of our lucky readers! Additionally, the grand prize winner — along with a runner-up — will receive one Defender case (valued at $50) and one Commuter case (valued at $35) specifically designed for the GS4. The phone is locked and doesn’t come with service, so those of you who aren’t AT&T fans may need to get creative with it. Hit up the Rafflecopter widget below to enter, and good luck! cheap Bluetooth Headset Note: Because the GS4 is locked to a US carrier, this week’s giveaway is unfortunately limited to our US readers.
