Not so sure! Remember the Qumran scrolls (at work, so can't check it up..) But essentially they were several thousand years old Torah scrolls that were found hidden away in a cave in an inaccessible mountainous area. When they were investigated, they found, if I recall correctly, that there were only a few letters that were different to the Hebrew "Torah" today! To Jews, it was a fantastic sign of the holiness of their Torah.
Yes the Dead Sea Scrolls have pretty much cleared up any Islamic complaining that the "bible was changed". The odd thing is that nowhere does the Koran actually say that the Bible was changed. This accusation must have come from later Muslims with no Koranic authority.
