I just downloaded insomnia and the insomnia sbsettings toggle...I didnt happen to see the toggle in sbsettings so I did a respring...the screen turned black and thats it! Ive done a respring before and have it hasnt been a problem! So I did a hard reset and the apple logo goes on and of sometimes with a loading whele under it! How can I fix this? This has happened before but I can only seem to fix it with a restore. I dont get any itunes errors either!
