Sweenbeen, you certain about this? Our Ms have the same native nfc tech and the samsung and nokia (which can beam via nfc between eachother) I had thought I'd read the m could too but I can't recall where I'd read it or how it would was done.. :/
I've played with this some between the M's my wife and I own.
Was trying to transfer pictures from one phone to the other and it never worked the way i thought it would. Every time I tried sending a picture, it sent the entire app i was using to view the picture with.
The M's curently will transfer things like URL's, and apps between phones but not pictures and videos...YET. The abilities of NFC will be expanded with the upcoming update to JB though so that we'll be able to use it in much the same manner as the Samsung phones..
