On the top of my Ipod touch, in the bar with the battery, is there a reason why nothing is showing in the bar except the time and battery? Shouldn't there be more? It's just a grey bar with the correct time and my battery life. Also, the battery like is very low and red on my main screen with all my apps, but when I plug it in and see the battery, it's full...plus I just charged it so why does the battery say it's so low? Helps appreciated!
