bluetooth problem - urgent

[Guest Tech]

hi.

My imate SP5m has been recently playing up

it disconnects from activesync randomly whenever it wants to, sometimes after 2 minutes of connecting and syncing, sometimes after 19 hours. I am connecting via bluetooth

Now, i have noticed today, just now, that the bluetooth on the mobile device seems to switch itself off, even after switching it back to discoverable, after connecting and syncing, it will disconnect from AS whenever it wants, taking with it, the bluetooth connection to off

anyone have any ideas?!
