Hi, I'm running BB V.0.4 and when I disable the "sync", the round "sync" icon stays in notification bar ?
I've seen that icon too. I appears/hangs about one in six boots. I'm a patient guy so I usually just reboot it again and all is good.
I've had issues with Weather bug not syncing too. Usually just delete and readd the widget and it fixes it. It seems to coincide with the little sync icon appearing.
