    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
    Size:61x53x12.5(mm)
    Weight:48g
    Capicity:1000mAh/1900mAh
    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)

    :D

    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
