I don't think it has to be fully charged. But at least 50% should be good. It's green when charging.how am i supposed to know if its fully charged? what color is the battery meter when its fully charged?
I had the same problem for about 5 minutes when I got my iPhone last night. I have a 15 inch MBP and for some reason if I plugged it in to the USB port on the left side of computer it would only recognize it with iPhoto, once I plugged it into the USB slot on the right side, it was recognized in iTunes as well.doesn't even work. hooked it up to the computer, opened iTunes, no iPhone icon pops up, no startup message, nothing. what the hell
