Exists an useful iOS4 Terminal App?
If by terminal you suggest SSH (or telnet) : I have actually made use of TouchTerm (ago when it was absolutely free, currently its 4$) and also iSSH.
I such as TouchTerm much better on the iPhone as I locate the semi - clear keyboard much better.
I favor iSSH on the iPad due to the fact that it has an actual iPad variation.
Additionally iSSH has a VNC customer and also an X web server that can be burrowed over SSH. Yet its 10$.
