For a quick tutorial on how to use SBSettings, watch the video above. SBSettings is a free utility for Jailbroken iPhones and iPod touchs that allows you to quickly toggle things like Wi-Fi, Bluetooth, 3G, brightness, and airplane mode. It'll also allow you to hide icons you don't want or use. (This is especially useful for hiding Apple apps like Stocks and Weather that you can't uninstall.)
You'll can also more closely keep tabs on your memory and running processes. This was extremely useful before multitasking. It's still useful today for freeing up memory and seeing what may be eating through battery or slowing your phone down.
There are also several plug-ins and themes you can download for SBSettings as well.
