Compatible with all jailbroken iPhone, iPod touch, iPad and iPad mini models running iOS 5.0 through 6.1.2.
If you don't know already, if you upgrade to Apples newest iOS 6.1.3 your device will no longer be able to be jailbroken, so if you want to continue to have your idevce jailbroke to run on iOS 6.1.2 or less, do not plug into itunes as your idevice be it ipad or iphone will automatically upload the current version of iOS which at this time is 6.1.3, there is good news for those who want to keep their idevice on iOS 6.1.2 until jailbreak softwares are released with Apples new operating system iOS 7. The solution is the semi-restore app which will be available in the coming weeks.
The semi restore app will be very easy to use and will partially restore your iphone or ipad without having iTunes upgrade to the newer version.
Semirestore would work like this: if your current iOS is 6.1.2 you can clean up your device and semi restore it to 6.1.2, It won't be a full restore, if it was a full restore you would be forcing the iOS 6.1.3 upgrade that patches the jailbreak holes, so in short semi restore will be useful if your iphone or ipad are running slowly or having other problems.
Please check back soon for more info on semi-restore and when semi restore release date is.
Remember for the jailbreaking to keep working you must not connect your idevice to iTunes for updates or you will automatically get iOS 6.1.3 which is not supported by any known jailbreaks at this time.
