Verizon stated that today they started the over-the-air (OTA) pushing process for all HTC Droid Eris users.
The main improvements and updates are:

• While on a call and the device is in screensaver mode, pressing the End key now takes the device out of screensaver mode, and a second press will end the call.
• On-call mute and speakerphone icon functionality is enhanced.
• Upgraded functionality after activation eliminates the delay users were experiencing in receiving their first call.
• Device now switches effectively from 1x mode to 3G.
• Device no longer requires users to reselect a default email after power-cycling.
• SMS and MMS messaging delivery is improved.
• Eighty-character MMS/SMS message subject lines are now allowed.
• Improved picture messaging functionality allows messages from LG phones to be opened
