I need SBSettings, adn the ability to change different themes, but otherwise I will wait for a non tethered JB, do not like tethered ones just in case...
There's a semi-tethered jailbreak out, which is almost as good as untethered...I assume you are worried about your phone being a brick if it restarts or turns off and you do not have access to your computer.
Semi-tethered means your phone will start up again, everything will work except Cydia, jailbreak tweaks, Mobile Safari and email. You can download Atomic Browser for free from the App store and that would still work to surf the web and check your email if needed. Phone calls, texts, and all apps will work. When you are back at your cpu, you simply boot tethered again and your jailbreak is back.
