this morning i woke up and realized my iphone 4 would not turn on. it will not turn on unless it is on the charger, but then after about a minute of being on the charger it shuts off on its own again. it registers that it is charged 100%, but if i take it off the charger the screen goes black and won't turn on. it will not pick up service, it just says that it is searching, nor will it connect to wifi. the time is completely wrong too. i cannot get it to reset either by pressing the home and top button. HELP!!
