Recently, I treated myself to a new iPhone and got myself the iPhone 4. I had been using the iPhone 3G and it was not working very well anymore and I needed a faster phone for work purposes. I love it. It's fast, it's sleek and having video is a major bonus. But as I walked out of the store, I was afraid to use it because I hadn't purchased a case. I knew what I wanted - I wanted a Mophie Juice Pack for the iPhone. I had one that fit my 3G and with the new shape of my iPhone 4 I had to get a new one. But it was my only option, here's why.
The Mophie Juice Pack is not only a sturdy phone case that will protect your phone from every day wear and tear (and accidential drops on the ground) to a phone charger! You charge up the Mophie Juice Pack and turn it off. Later, when you're out and about and low on iPhone battery, you can turn on the Juice Pack and it will fully charge your phone again - giving you several more hours of use when you're not home and unable to charge.
It's not cheap but I look at this as a dual product - not only a phone case but a battery charger. Get the Mophie Juice Pack for the iPhone at various retailers for $50-80 depending on the store and the iPhone version you have.
