i have an ipod touch 3rd gen. and an iphone 3gs. the ipod is useless due to a short in the touch screen, and the iPhone 3gs needs a new battery. given that both are out of warranty, will i be able to use the iPod battery to power the iPhone?
No it won't work because the iPod battery is smaller then the iPhone 3Gs battery and the iPhone 3GS battery takes more energy do to the data and all that.
