I had the same thing happen with my new 7100T.
I liked it on my 7510, but it wasn't there when I got my 7100T last week, so I thought it was a vallue-add from Nextel.
I had to grab the latest handhled software so that eOffice would load, even though the handheld already had the .198 build on it. During the "update", Password Keeper showed up in the Application loader, and I was able to get it loaded.
