So, an update. I ended up changing devices, becasue I could not go without work integration, so I went with a Rezound. I worked with our IT team and IBM tech support to find out that our corporation would need to update their server to support ICS. I knew this probably wan't a possibility, but when I forwarded our adminstrator a link of phones that would eventually be getting updates, and that a couple of our VPs used those devices, they scheduled the update. They updated the servers this Wednesday, and I bought a GN on Craiglist yesterday ($350 off contract, yeah) and plan to have the software installed tomorrow morning. I'll update with the results.
