installing bluetooth on my r40e 2684 HVG

[jet]

my thinkpad model is r40e 2684 hvg
which part do i need? read on one of the bits of paper in the box that this thing does have a bluetooth aerial in it.
read in the T forum that you're supposed to replace the modem daughter card for a bluetooth/modem one? anyone got a link to this on the ibm site? i've taken a look but i'm finding the site impossible to navigate.

i'm in uk btw.

i'm also thinking of getting a a/b/g mini pci wifi card, anyone know if i'm likely to encounter problems during installation? and is £45 too much or a bargain?
and what about this one? any idea the max one should bid on it?

I have a TP R40 (2897-54U) that I would like to upgrade to Bluetooth too. The FRU for the card I need is 91P7259. Unfortunately I don't think my TP has a BT antenna so that is a problem unless I want to void my warranty.

Does anyone know if there are any 3rd party antennas that can be used without voiding the warranty?
