So your shiny new iPhone 4S finally arrived. Now it's time to outfit it with some killer accessories.
I'm talking about a Bluetooth headset designed for runners and cyclists, a backup battery that'll keep you talking and texting until you can get back to the charger, a custom case adorned with a photo of your loved one(s), and a lot more.
Oh, and there's no need to feel jealous, iPhone 4 owners: most of these accessories are compatible with your model, too. (In fact, many of them will work with earlier iPhones as well.)
