I have the iGo Stowaway Bluetooth Keyboard (not the one for the BlackBerry).

I can pair my keyboard with my BB 8700c. But typing on my keyboard produces no input in MemoPad, email or SMS.

Doing a search, I edited permissions to permit keyboard injection and browser filtering (I am on a Hosted BES).

Is what I am trying to do "Mission Impossible" because my keyboard requires a BT profile OS 4.2 doesn't support (and I have to buy a second BT keyboard geared for the BB to make this work)? Or is it possible, and I just haven't done something right?

Take a look at this thread covering the Blackberry BT functionality w/your current keyboard model (not dependent on OS version):

Thanks. It appears what I am trying to do is not possible with this keyboard. Thanks again.

I upgraded to OS 4.2 and the Stowaway keyboard continued to work fine (if you can call a portable keyboard without a means of turning off "fine"). Issue is not the OS.

Do you have the Stowaway that is particularly for the BB, or the one I have (links to both are in my initial message)?

There is only one BT keyboard currently available that will support both the BB and other smartphones/PDA's. Check this thread:
