I'm using another computer than normal to do iPhone dev.

Now I'm trying to get my apps onto my iPhone, but fail with the certificates, keys and stuff. Refer to this thread: http://stackoverflow.com/questions/613719/iphone-provisioning-problem-public-private-key

Actually I'm able to download my cert no problem from Apple's site, but how would I get at the keys needed? (private, public), I see no way of getting them...
