Well I am going to try tomorrow at lunch to see. I might just end up mailing it in and see what happens. Interesting thing though, I did a restore to mu 5.7.893 stock-rooted and then did a factory restore with wiping the internal and external. I had already moved on from The Bionic so the Sim is not installed, it wouldn't even get past the "Touch the Android" screen without the Sim. So no way to actually check the version that way.
Funny thing though, the OP said something about their OG Droid taking a bath and getting the Bionic. I got my OG Droid because my iPhone (ATT) took a bath (washing machine). My first Android phone and I haven't looked back.
