Anyone have any tips on trying to copy a long SSH private key to my BlackBerry 7250?

Some things I've tried:
1. Create a memo in Outlook or your email program and paste your key
into it. Then synchronize your BlackBerry using IntelliSync and then
copy the key from your BlackBerry memopad and paste it into Mobile SSH.
This way the key is loaded over your USB or serial cable.

2. E-mail the key to yourself, which is not very secure if you don't
have a BlackBerry Enterprise Server and can introduce unplanned line
breaks.

Still, I get an error about "Unable to decode OpenSSH private key" (using Idokorro SSH client).

I'm assuming at this point that my problem is simply new lines that have been introduced during the transfer, but it could be something else...

paste it into a different shell session..

obvously you have to take a security risk to copy it =)
