The iPhone 3G may be called as a phone with the best battery life in competition with other 3G handsets, but that still doesnt change the sad fact that its ridiculously necessary to recharge the handset everyday. Sometimes even twice a day. Its not extremely difficult to foresee a situation where you need to use the handset badly but the battery has just died on you.

Since the geniuses at Apple wont allow you to simply buy another battery and plug it in when that happens, it leaves you effectively stranded. Unless of course you had the foresight to buy one of these cases which come with a rechargeable battery.

This case comes included with a built-in high capacity li-ion rechargeable battery. The sheepskin case keeps the edges of your phone protected from wear and tear, while the battery (built-in) makes sure you never completely run out of power.

At just 25$ a pop, its worth the cost of the cover itself.
