Many people ask me why they should jailbreak their iPhone and whether it is safe. I mean like I'd be there forever explaining all the benefits, and I'm sure other jailbreakers will agree with me. It's also completely safe. There's like 0.0001% you'll ruin your iPhone - that figure is completely made up, but you know what I mean.
JailbreakMatrix have thankfully put together a video listing 100 reasons why you should jailbreak your iPhone, and it pretty much covers everything. It's only 3 minutes long so it's worth watching. I don't get why they added the awkward girl in it though, very cheesy if you ask me.
