A: We have one answer - not yet. : A downgrade option won’t be available, too – it won’t be so hard to inject this option, but it will only burn parts of known tools which could be fixed quite fast by Apple. Summary of this – no downgrade option yet! Maybe. Wait.
Q: if there are currently have any plans upon the next big release for Apple’s iOS 7.
A: “yes”! We already have some parts of the tools which could be used to Jailbreak our iDevices. The fact is, we won’t burn any tools for any option on a new version for the Evasi0n tool. About a re-restore option for all iDevices on currently JB ones, the answer should be now definitely be clear for everyone.
