    Maybe there are some in ebay or other website, It just like a out side bettery. It means it have a Dock and if you want to charge, you can put it into the Dock on the iPhone.Like this one(pic.):[​IMG]

    but, you have to charge the backup bettery before, then charge the iPhone if you need.

    Some thing about this:
    Type of the bettery: Li-ion
    Out: 5V 500mA
    In: 5V 400mA max
    Time for charging: 2 hours.
    You can use it on:
    Apple iPhone 3G 8GB 16GB
    Apple iPhone 4GB 8GB (2G Version)

    (It might be can use on 3GS, maybe this one producted before 3GS)


    It just cost 60RMB in China.
    It just like $8.75 today.

    So, it's cheap. And about the cost pf post, maybe $10 to $15
    It is very cheap!!:D
