this was posted at www.androidforums.com. it gives a full list of what will be in the update for the eris. it is coming but it does not say for sure when. i am running a "leaked" version of 2.1 that came from htc/verizon and it works great. just thought I'd share the news.
Also just for everyone's information. There is a way to hold off the OTA and copy it from the phone before you dl and install it on your phone. Please check http://androidforums.com/htc-droid-eris/77290 -people-about-do-update.html for the steps on how to do this.
