Actually, it shouldn't be all that difficult to hook up, but I believe you would need a level-shifter for the I2C lines
, since I don't think the Shield has any jumper points where you can access 3.3V signals.

with a link to this thread, we'll be happy to exchange the shield for the breakout board.
If you decide to stick with the shield, post back here and we'll talk about hooking it up
