I updated my iPhone back in September to the iPhone 4 and have had absolutely no problems with it untillm y battery became low and proceded to turn off and now it won't charge or turn back on and I don't know what to do or whats happened??
If you live near a apple store take it to the genuis bar. They replaced a dead battery on my son's iphone 4 even though it was no long under warranty.
I believe there is a one year warranty on the phones hardware. They should replace your battery free of charge.
