Official Website released iOS 7.0.3 Untethered Jailbreak : http://ios7jailbreakfree.com/
-evasi0n 1.5.5 is an untethered jailbreak for all iPhone,iPod touch,iPad and iPad mini models running iOS 7.0.3
Backup your device using iTunes (or iCloud) before using evasion. If something breaks,you'll always be able to recover your data.
Please disable the lock passcode of your iOS device before using evasion. It can cause issues.
Avoid all iOS and iTunes related tasks until evasion is complete. Why not just enjoy a brief break from the computer to stretch your legs?
If the process gets stuck somewhere,it's safe to restart the program,reboot the device (if necessary by holding down Power and Home until it shuts down),and rerun the process.
If you get an error on OS X 10.8 saying that evasion can't be opened,control-click (or right-click) the app and on the revealed context menu,choose 'Open.' On the ensuing dialogue box,choose 'Open' as well.
