All member : Can do this :

If u have shsh ( 5.x ) u are safe to downgrade via redsn0w or ifaith without any pb
only ios6.x have this pb to stuck in dfu

if u don't have shsh and want to keep safe ur gevey follow this step :

1. Open Latest Redsn0w
2. Go to Extras
3. Even More
4. Restore ( Choose 6.1.3 )
5. U will show ( YES -- NO ) click YES ( to save ur bb )
6. After done ( open again redsn0w -- choose extras select ipsw 6.0 -- back to jailbreak button )

After that u will see some tick ( install cydia , api ticket , deactivate etc )
remove all tick ( without any tick ) click next ( this will only hactivate ur phone )
after done ( not work only mail and safari ) but don't care about this ( u can install delphin or chrome browser and any mail to ur iphone ) and enjoy Untethered phone ( without cydia ) u can turn on and turn of any time u want and use ur phone like untethered.



Best Regards
