Hi all, I am looking forward for ios 4 but one of my friend already have it and when I discussed about ios 4 he was happy with it but he was not happy with the battery life of its. As per him it has a worse batter life w/ the GM Candidate than w/ 3.1.3.So, because of it even I am not able to make my mind .can some one tell me who is using a ios 4 about its battery is it really worst.kindly share your views with me so that I can make my mind accordingly.
