What Do I Do After I've Jailbroken My Iphone?

I jailbroke my iphone using green poison & afterwards my phone flashed & then went off & I immediately turned it back on, but when it came back on i didn't see the cydia app that the website said would be there. Did i turn it on to quick? Is that why the app didn't show up Help

Ugh… Don't they warn people NOT to jailbreak their phones? It's permanent and you can't undo anything! You just messed up a perfectly good iPhone, congrats.

Plug it in to iTunes, restore it, and then jailbreak again
