Newly arrived in the App Store is pTerm ^[1], an iPhone port of the PuTTY terminal emulator. It supports SSH and Telnet, among other things, and has a built-in Control key.

Eric Maland says that a 1.1 update is already on its way (it has been submitted to Apple and is awaiting approval). Unfortunately a handful of "major crashy bugs" (as Eric puts it) were discovered after the 1.0 release had been submitted.

Planned features for future releases include multiple simultaneous connections, custom sizes and colors, port forwarding and lots more.

And in the meantime, if you download and experience crashy behavior, Eric's message is: be patient. The fixes are done, but when they reach the Store is out of his hands.

pTerm is $4.99US in the US App Store ^[2]
