    I am in need of some quick help.
    The battery in my 4S is going bad, I can barely use it for half a day before it dies, after charging to 100% in the morning! I am going to get a used iPhone 5 for my bday in December, but I still want to use my 4S till then, so I'll need a working battery. So, can I take the good battery from my 4 and use it in my 4S?

    At the iPhone hacks section.
    You can get one for it on eBay or online for cheap.
    Like $10 or so.
