The last couple of days I've noticed I can't browse or update apps like Android Facebook, Android Twitter and Google Mail and can't browse the Market when I'm connected to the mobile network on 3. This happens even when the notification tray has the H or G symbol and up- and downstream icons are animating. I've checked through the Mobile Network settings and can't see that I've changed anything by accident. The strange thing is the Friend Stream updates when I'm connected to the mobile network. Does anybody know what I might be missing?
