ok i just got my iphone and i wanted to charge it first (thats the first thign u do before anything else right?) anyway when i stuck the plug into a power socket and connected it to my iphone it gave me an icon that signaled me to use a usb cable to connect to itunes and gave me the option to "slide for emergency" or something? emergency? what emergency?!! help is someting wrong? also i turned off the phone to let it just sit there and charge but i dont see any kind of green battery icon or anything??
