Yes .. I repeat .. what happened to it ? ??
It (the primary(?) ELT) went to the bottom of the Equtorial Atlantic with the rest of the wreckage. As it got to greater depths the bits that had airpockets were crushed. That's what happened to it.
ELT's quite often fail to activate in serious crashes (though they sometimes activate on hard landings
). Even it AF447's ELT activated on impact, the signal was - literally - drowned out as the wreckage sank.
