I purchased 'ssh client' for iphone, which was $1.29 - the cheapest paid ssh app for iphone. Pretty rude looking compared to p-term, which I had used previously. ssh-client works ok for linux and cisco, but carriage return is a fail for my mikrotik gear.
I found a free ssh client for iphone called zaTelnet, which works ok, although I don't like the keyboard as much as the standard one that p-term uses.
Looks like I will be paying the NZD$6.49 for pterm. It also supports colour :)
