1)You know when you press the power button and the lock screen shows up and there are little envelope icons that tell you the number of emails/texts/messages you have? When I look at mine it says I have 6 emails, but when I check my emails I don't have any new messages. 2)Sometimes I can't open my music or the market place. When I click them the screen goes black and says, "loading" then it just goes back to the main menu. Any ideas on how to fix these problems?
