What do you do when you need a quick respring after modifying your iDevice? I go into Winterboard and toggle 'summerboard' on and then off. In the upper left corner the respring toggle instantly appears and I use that. Takes a second or two and allows my iDevice to respring without hassle or trouble. I know this simple method isn't going to light the world on fire, but I was at an iPhone repair shop yesterday getting my screen replaced and the technician there was turning the iPhone off, waiting for the iPhone to then cycle off, and then turning it back on. When I suggested what I did above he seemed mildly surprised. Just wanted to share this tip here. . . Carry on!
