Telling what version of Ubuntu you are running is extremely easy. You  would commonly use this command to figure out if you are running Edgy  after you upgraded from Dapper.

cat /etc/issue

Ubuntu edgy (development branch)

Note that the version numbers might change over time. I’m running the  beta version so that’s what shows up when I run that command. Either  way, it should be clear that you are running Edgy.
