There have been taster applications in the past such as "Meet Symbian Anna" http://store.ovi.com/content/180379 but not aware of such for Symbian Belle. Have you also checked what is available via Nokia Suite > Tools > Software updates?
Running Belle upon my E6-00 but free phone memory does have a habit of disappearing!
What I do find is that E6-00 now seems so slow compared to my 700 which was overclocked from 1Ghz to 1.3GHz with release of Belle FP2.
