If the logic board on this phone is still intact there is hope :) how bad is it ? is the chassis all bent out of shape ? can you elaborate a bit more on the damage ? as i was saying ... if the logic board is still intact you may be able to put the logic board in a different shell. unfortunately the storage of any iPhone is a chip on the board, so you can't extract the storage and put it on an other phone. upload a couple of pics maybe i can help further
iPhone logic board
it looks like the logic board has been split or partially severed ... the only hope the phone had is if the logic board was "intact" which it looks like its not :( The phones DATA has in no way to do with what the sim holds "as DATA" sim: some numbers and you phone number info. Phone Memory which by the way is a crucial part of the logic board : pics, numbers apps, music. to make a long story short ....
if the logic board is not intact ( as a whole, like the picture) it can't possibly be mended ;(
