So I just tried TSMobiles and RDM+.
RDM+ is not an option to me because it required installing something on each server to work.
TSMobiles works, but at least on the blackberry 8830, it's annoying that clicking the pearl button doesn't do a mouse click. You have to hit the menu button, select mouse, click, confirm, etc. It also has problems with scrolling.
What I found. Assuming you have citrix, Idokorro makes a citrix client(not free). This connects to citrix(realize it's connecting from the BES server, so use your internal ip addresses.). Then all you have to do is publish mstsc.exe to your domain admins, and wala, you now have remote access to your servers from your blackberry. Select to zoom out once you connect and it works pretty good.
