PuTTY

A.3.8 Will there be a port to the iPhone?

We have no plans to write such a port ourselves; none of us has an iPhone, and developing and publishing applications for it looks awkward and expensive.

However, there is a third-party SSH client for the iPhone and iPod Touch called pTerm, which is apparently based on PuTTY. (This is nothing to do with our similarly-named pterm, which is a standalone terminal emulator for Unix systems; see question A.3.2.)
