Its pretty good

Only reason for four stars is because I cant seem to get it to "ding" if I get a message. It just a shows up in a banner, and I have it set for sound, badge, and banner..... It would be great if I could get that to work. Its just inconvenient because I dont notice I have a message until much later.
