My wife's Verizon iPhone 4 is JB'n using Redsn0w. It is on iOS 5.01. Used it to make a call about 8:15am then went to bed. Got up at noon, it won't power on. Connected it to a charger for about 45 mins to ensure it wasn't dead. Tried holding the sleep/wake button and home button at the same time for about a minute. Nothing. Plugged it into iTunes. Nothing. WTF do you think happened?? Any expert advice is greatly welcomed. Thanks!
