Hello, I have a question. I used iOS 5 beta 1 and 2 and I barely got a days worth of battery. I jumped back down to 4.3.3 and battery has been a lot better. Although, I miss iOS 5 a lot and was wondering if anyone is on iOS 5 beta 5 ( I think that's the latest ) with an iPhone 4 and if the battery has improved. I know beta's arent optimized for battery, but I was wondering if it's better. Thanks in advanced.
