I decided to jailbreak my iphone again so that I can access the terminal as root, create wifi for my ipad, facetime without having to be connected to a wifi point, etc.

Jailbreaking for the iPhone 4 OS with it’s multitasking support is a whole new architecture but surprisingly most jailbroken apps are already working. MobileTerminal unfortunately just crashes when opened. After doing some research I found that it hasn’t been finished being ported yet but you can install a prerelease copy through the following steps:

- Download the 426 version from http://code.google.com/p/mobileterminal/downloads/list
- Rsync the folder to your root/Applications/
- reboot (you can just type reboot right from your desktop SSH session if you’re lazy.)

I’ve tested out SSHing into a few boxes with it as well as using the gestures it allows you to set up. Working pretty sweetly. Now I just need to find out how to enter the meta key…
