I have had my iPod jailbroken, with blackra1n on my Mac, for about 2 weeks and all of a sudden when i respring, none of my apps respond. i click on one, it goes dim, and then nothing happens. I tried rebooting my iPod but it did not solve anything. the only way to get my apps to work is if i lock and unlock my iPod but when i respring i have to repeat. does anyone know what could be happening? im running 3.1.2 fw. Thanks.
