I just got the ip5, i've previously owned all the other generations, and my new iphone5 never send updates to the lock screen, i've check notification settings and i have it allowed. Gmail for instance used to within seconds push my mail to my lock screen all day, but now my mail box only updates when i actually open mail. its pretty annoying to refresh all the time. anyone encounter this issue and have a fix? same goes for facebook messages and notifications.
