I also lost the volume button, this isnt a soloution but it helps....i always use a pin or somethin thin and sharp to push the notch up or down inside where the volume button was....it dosnt resolve the problem but ive gotten used to it and the volume dosnt really bother me now...
This has also happened to me - I put a thin strip of plastic in front of it to stop it falling out. I am going to the Sony Centre soon to fix that & my battery issue before my warrenty runs out.
Hey there i have the same problem only difference is mine hasent fell off yet but mines broke while i was simply turning the volume up! and it happened the day i got it...i was not best pleased! lol
