Bluetooth stack

[elesbb]

I have them included .. But I was reading somewhere (on google) that all the stock ROMs or the rhodium have the widcomm stack .. I was toying around with my kitchen last night and noticed I can comepletely replace the SYS folder while keeping the OEM and ext packages . So im wondering if maybe getting and HD2 rom and extracting the sys packages from that and mixing it into my kitchen will replace the bt stack .. Im not sure if the bt stack is in the sys folder or the OEM packages ..
