Give Prompt (from Panic) a shot. Much much better than iSSH IMO (if you need just an ssh client, not VNC or other crazy stuff).

And for VNC, "Screens" is the best: http://itunes.apple.com/us/app/screens-vnc-control-your-comp...

I've only had bad experiences with Prompt + 256-color vim/screen, but I've hear it works better with tmux.

Prompt blows me out of the water. I love using it.
