Left phone to charge overnight now completely dead. tried hard reset still unresponsive, unresponsive when plugged into computer or other sources to charge. charging dock was not new and is regularly used by both me and my gf her ipod is fine. this is the first time my phone has done this. anyone know how i can get it to start back up again? so far everything i have tried doesn't seem to work, nor do any of the solutions found posted in the forums.
