Checked the 7130e downloads at verzion and there's a sofware update for the 7130e dated 3/14/2008 . . . Verizon Blackberry Downloads
Looks like it's version 220.127.116.113
Update: Installed it last night. The first improvement I noticed was speed: The BB Gmail app used to take 8 seconds to load, not it loads almost instantaneously. Internet seems much faster as well (Page load, app launch).
