Jailbroke my ipt 2g mb a couple months ago, been pretty content with it ever since. But, I have a couple of questions.

1. Can I re-jailbreak my ipod, deselecting multitask this time, without losing any jailbreak apps? Sometimes the processes left from every app I open can make my ipod laggy, and I'd just prefer to remove it seeing as the switching thing just crashes anyways.

2. Whenever I follow a hyperlink in-app that is supposed to take me to another app (i.e. Facebook to safari, safari to youtube), my springboard will crash and I won't be able to use it. Why is it doing this, and is there any fix?

Thanks for any input you can give to help
