I just found a leaked build of android 2.1 for the eris, tempted to install it, but think I will wait till the official build comes out, which should be soon, was promised for 1st quarter 2010.
though reading all the posts, no seems to have had a problem with it yet, but it is still too soon to tell a far as I am concerned.

if verizon doesn't post the official rom as promised, then I will try it out.
