This post talks about the new very very easy to use jailbreak. Just point your iOS device safari browser at:
No need for mac or pc to jailbreak with this - do it all from your iOS device. However there is the issue the there are some issues.
I would highly suggest you hold off right now - as there are still some tech issues - especially with Facetime and MMS.
I am sure there will be updates on this coming soon.
If you do decide to do the jailbreak - please give your feedback below.
