Concern about general problems such as slowness and battery life on gadgets isn’t unusual, but using iOS 4 on the iPhone 3G seems to make the problems so bad that the phone is nearly unusable for some people.The WSJ was told by Apple they are looking into this matter and they might be already working on a possible fix.
