Nokia 8801 / 8800

I was looking at the specs for this awesome looking phone, noticed that it will support stereo (very cool, and i understand that) and sim access. My questions are:
1. What is sim access via bluetooth?
2. Under MMS, it mentions a lack of OBEX support, can somebody elaborate on if that means nokia went all verizon on us and crippled the obex or you just can't transfer the MM's via bt.
