After installing SBSettings, I want to be able to avoid rebooting as my iPhone has got stuck in a loop and reverts to black screen. If I want to install SBSettings after JB'ing my phone for the first time, what is the best approach?
You cannot avoid rebooting your iPhone. Installing certain things simply require a reboot. Make sure your iPhone's plugged in when you get ready to do so, so you can run Blackra1n again and avoid heart attacks.
