Hello,
when google does a PR update does anyone know how old the data they take is ? is is a year old, 6 months old, 3 days old ?
I also heard there are different kinds of PR update ( minor and major ) could someone tell me more about this ?
Thx,

Most of what Google has told us in the past is that the PR data is usually in the area of a couple weeks or less at toolbar export time - there's no way for us to check on that, of course.
With regard to minor updates, this has been happening for a few years now. By minor update, I mean only a relatively small number of URLs see their PR change.
It seems like there are at least two kinds - completely in between full PR updates, and almost immediately after a full update. Just from watching, it seems like the right-after-a-major-update type sometimes happens in order to correct parts of the full update that had data export glitches of some kind. The minor updates that happen completely in-between major updates sometimes hand out those toolbar PR "penalties" for sites that were selling links. But that certainly doesn't explain every case I've seen.
