when i tryin to format my mmc it gives an error like appservthread closed and dont format mmc.i try a lot of times to format it gives this error and starts to format.
and the
other error is when i change phone language or sim card ngage opens and gives this error "BTserver" closed and i push ok, it works normally.
I don't get any problem in the future. But if want to prevent this error, try to hard format ur phone memory using key *#7370# (but, u will loose ur contacts, and all the setting that u have enter it manually like mail, gprs).
s.a. 
Linear Mode
