Ok so I'm running on jailbroken 2.2 and I was sitting in biology class chillin in safari and I clicked the home button and the springboard started to restart and I was like ooook? So I let it do it's thing and my back round was gone and it popped up with a message that said "springboard crashed. And a whole bunch of other stuff and that my device was nor running in safe mode". Should I be worried or like unjailbreak it? Is this normal? Thanks for the help.
