If you're annoyed by mobileterminal's tendency to flip upside down when you launch it on 3.0, or if you just don't like it, then you can substitute it with one of the many SSH apps on the App Store. Note: This will also work on 2.x or 1.x. It will NOT work on non-jailbroken ipods. 1. Download/Buy a terminal app (A good one IMO is iSSH) 2. Open up the app. And add a new host. 3. This is the most important step! Under hostname, enter localhost 4. For login, enter mobile or root, depending on if you want to default to default to superuser (I would recommend logging in as mobile, then using su or sudo for superuser commands). 5. Save and connect. (This doesn't require wifi).
