IPHONE Model: MC676LL RAM: 14GB (10.4 Avail) CODE Ver: 4.2.6 (8E200) PROB: Symptom: My Iphone went dead at work. 1)I tried plugging into the car charger thinking the battery was dead, but no charge and no charge indication = still dead. 2) I tried my home charger, (thinking it was the car charger) but I got the same symptom = still dead, nothing nada... ACTION: I checked you tube and found this site FIX: 1) I checked this site and came across the suggestion above to "by holding down the sleep/wake button and home button simultaneously" and it worked. I entered the security code and all is in order.
