My phone says "currently unable to send message, it will be sent when the service becomes available" when I try to send pictures. My phone has full bars and doesn't have a problem sending anything else. It just started doing this last week and hasn't let me send any pictures since then. I heard something about resetting the phone, but the ON/OFF button doesn't work so I can't push power button and the front button at the same time to reset it. Any ideas?
