few problems with G800

hey, I recently purchased a G800 and im having a few problems with it.
Dno if anyone can help me with it.

Start with the worst.
I have an apply macbook and when ever I try to bluetooth something from the phone to macbook, the percentage complete bar on the phone appears for a second before coming up 'sending failed'.
This doesnt appear to be the phone or the laptop as I can send things fine to my ibook from the G800.
But also, the macbook can bluetooth to the phone and the laptop worked fine with my previous phone (sony K800i)

the other two problems are annoyances more than anything.

1.
If I type a message and click send then just close the phone the phone cancels the sending.
I have to sit there and wait for the progress bar to finish before I can do anything.

2.
Any txt messages I receive and placed straight onto the Sim card rather than the phone untill the sim card is full at which point it starts putting the txts onto the sim card.
Is there anyway to make the phone to default storage device?

Cheers,

Tom
