I was going to say something against this, but I found out a few secs ago, how useful this would seem.
how? it wouldnt be useful from a accidental getting tripped up the cord you know. the iphone doesnt have enough mass really for a magsafe to be effective
I don't think it would work as well as you think, simply because the phone doesn't weigh as much as a laptop computer does. Unless they made the magnet much weaker for the iPhone version, the phone would still get knocked onto the floor before the magnet would come out.
lol maybe i should continue to read before i post it seems
