If you have yet to jailbreak your device, you should do so soon. Apple has already seeded iOS 8.1.1 to developers which breaks the Pangu jailbreak. You can find instructions on how to jailbreak your specific device using the iClarified Jailbreak Wizard.
in my opinion this is a waste of time for the developers, why not dowload virtual box and win7 and also vise-versa when there is only for mac
the focus should be on keeping it JB alive
