Ok, perhaps an sbs icon icon then? Not all of them are toggles, for instance the brightness icon pulls down a menu where you can adjust. Is there something similar but for wifi?
I think this will work for you. After you install this tweak, hold your finger down on the Wifi Toggle in SBSettings and it will open a menu that lets you change the wifi network.

Nice, I didnt know this existed.
Let us know if it works/function right on the latest JB cause it hasnt been updated since early 2010.
Honestly, I have never used this tweak, but I knew it existed so I shared it. Sorry if it is incompatible with iOS 6.x
