I know a guy with a 1337 1.5 PSP.
1.5's awesome. You can emulate all the other firmware versions (that are worth emulating, at least).
Towards bleed,
I don't know if you're much into programming, but most programmers do it by x.y and sometimes x.y.z, because if something is a minor update (usually bug fixes), they'll increase y, and not x. If x is increased, then it's almost always a major update.
EX: Firefox 1.5 -> 2.0
That was a MAJOR update.
