I'm still new to JB.. when I JB'd 2.1 I installed a program that allowed you to open SSH/WIFI/3G, etc with a swipe of your finger across the top of the screen.
That's SBSettings. I just deleted it on my phone and put regular BossPrefs back in. SBSettings is too unstable IMO. Have you ever gone into Safe mode for a simple respring using SBS?
