Does anyone know the battery capacity for a 3g Touch? I have a 64 gig, but it would be helpful to know the 32 and 8 gig specs as well if they are different. I've been through the apple website, user manual, and asked around at my local electronics stores, as well as in an apple store itself, and no one seems to know. I'd like to know the mA/hr (othrwise known as capacity) I'm guessing somewhere in the 800-1000 range? If you could say where you found this information it would be twice as helpful. Thanks!
