I know you said that you are not one much for cases, but LNK: this one caught my eye. It has the same appearance as the back of the phone. I also heard UAG was developing a case, so fingers crossed.

EDIT: As far as bluetooth LNK: this one looked interesting to me. It got good reviews.

I use this to connect through the audio aux jack. Works awesome.
