External battery packs for the iPhone aren’t exactly the most flattering accessories, but we’ve found something that will probably make you change your mind.
The Incase Power Slide is a protective case and battery pack all rolled into one stylishly designed product for the iPhone 3G. It also comes with a custom USB cable so you can charge and sync without having to remove the iPhone from the Power Slide. It comes with 1330mAh 4.2V rechargeable battery that provides up to 330 hours of standby time, 5-10 hours of talk time and internet usage of up to 6 hours on 3G/WiFi giving you more time to enjoy your iPhone while on the road. There’s a LED battery status indicator at the back that shows you how much juice is left on the Power Slide so you recharge it accordingly.
If you’re an avid user of the iPhone and find yourself on the road most of the time, this is one accessory we’ll gladly recommend for your cell phone buying this holiday season. No word yet on pricing a release date of November 28th has been scheduled.

BEWARE WHEN BUYING
=====================
This looks great however it cuts your signal by about 20% when it’s on the phone.
Certain cities with strong cell towers like Houston and Tampa this worked great, worth
every penny! However cities like Milwaukee and Chicago this was terrible!!! Every call
was dropped until I removed the case. When it works it’s awsome, however the results
vary from city to city as I traveled. I would not purchase this unit again if I had a chance
because it is worthless in those cities. It’s a great extra battery for watching movies
on an airplane though.
