Multiple 9.2a updates for Series 3?

[PeteTV]

Has there been more then one 9.2a update for the Series 3?

I'm quite sure I've seen the "You have a new service update!" message at least 3 times and possibly 4 since October. Each time it says the same information about the "Fall 2007 Service Update" and "Amazon Unbox/Expandable Storage".

I can't remember for sure if the version string was the same for each one, but I'm pretty sure it started with 9.2a (via Messages & Settings->Account & System Information->System Information->Software Version)

Is it possible to find:

1) a more specific version string?

2) a log of what updates I've received?

There was the update to 9.2, and then 9.2a (widespread public release).

1) The full version string is at the top of the Messages & Settings->Account & System Information->System Information screen.

2) There is no log of updates.
