My mother-in-law asked me to make her phone faster like I did for my brother-in-law, meaning root, a ROM and an overclock if its possible on the Eris. According to the Sticky, these are the Froyo ROMs available for the Eris:
Cyanogen Tazz-By tazzpatriot
CELB Froyo-By Conap
What is the best rom in terms of stability and speed without an overclock. I noticed Buffed is overclocked already so it is possible, but I want a stable one for her so she doesn't call me every other day because the phone is acting up.
