Bodymedia Link questions

I have a few questions about the Bodymedia LINK and how it works. I posted this in the Bodymedia group but was hoping to get more comments.

My understanding is that one of the ways it measures is by your body heat. I am a very cold natured person, for some reason I just can't seem to get warm most days even in summer. I shake and shiver year round, so would this cause the Bodymedia LINK to be inaccurate for me?

I know it syncs to some Apple devices. Can I sync it to my iPad 2 and my 5th generation iPod? If both are compatible, can I switch back and forth between the two devices?

I was born missing my left arm from about 2 inches below my elbow due to Amniotic Band Syndrome. My understanding is that the armband is worn above the elbow so I am thinking this would not have any effect on wearing the device for me, is that correct?

Several people on the forums have stated they wear their armbands on their calf at night because it is more accurate. I have also saw several women post they place the sensor in their bra. Would those two alternatives give accurate readings?

How has this worked for you? Are you losing the amount it says you should on average?

Thank you so much for your time. Have a wonderful day.
