iOS 5.0.1 Software Update Issue

There seems to be some issues on "Contacts" and battery life surfacing right after the latest iOS 5.0.1 software update, many complaint that the update doesn't fix the battery life problem that Apple promised. Some iPhone 4S users even said that the update make the battery life worse. So far, not much about its effect on iPad and iPod Touch has been discussed. But for those who want to be on the safe side, you should hold on and wait for the next update. I'll be testing it on my iPad2 as well and will be updating all my readers about this issue.
