My iPhone 4 is right next to my laptop, and when I pressed the home button, nothing happened, so I assumed it was dead. I held down the power button to make sure, and the battery icon didn't show up. I put it on the charger anyway for a few minutes, and nothing happened. What should I do? I am running iOS 5, and my phone is not jailbroken, nor is it unlocked. ---------- Please help ASAP!
