I have just jailbreaked for the first time and i'm having some problems. I ran redsn0w and also unlocked with yell0wsnow. i have a 3G running 3.0.1. I downloaded a couple apps in Cydia and that went off without a hitch - but the problem lies when I try to actually open the apps. I get a screen that looks like something is happening, but then it just shuts down and goes back to the springboard. I've tried restarting the phone - and tried it with a few different apps but with no luck. Is there possibly something that I haven't done correctly or a step that I'm missing? thanks for any help in advance!
