2.1 was the last official update for the Eris. There are custom ROMS running 2.2 and 2.3, but you would have to root the phone to install them. It's not that difficult to do and is explained very well in the "All things root" subforum.
Look through the "Universal Root for Dummies" thread if you are interested in rooting the phone. It gives very good step by step directions. None of the developers are still working on the Eris, so the ROMS that are out there will not be updated any further.
The best ones out there seem to be:
xtraSense (2.1 Sense-based ROM). Similar to stock Eris
xtrROM (2.1 ROM w/out Sense)
Condemned CM7 (2.3 Gingerbread)
GingerShedBread/GSB (2.3 Gingerbread)
2.2 (Froyo) never really ran well on the Eris. I would either stick with 2.1 or go to 2.3.
Do NOT load KaosFroyo or KaosGingerbread. These ROMS were never really completely finished and won't run well unless you make a lot of modifications to the settings.
