A couple of days ago, Apple have released new iOS
a
version to 6.1.3 and unfortunately,
you cannot jailbreak it these days. Then only way is a
downgrade. If you are using iOS 6.1.3 you can
have a jailbreak it from downgrading to iOS
6.1.2
Most of iDevice holders know what the
downgrade is; actually, downgrade is installing lower iOS
versions.
Most
of
the people need the better advantage in their iOS,
at
this time they are going to upgrade to the iOS
6.1.3 as I say above there are difficulties on these days about iOS
6.1.3 jailbreak. Then
you need a good tool to downgrade,such as snowbreeze to create IPSW.
If you accidently upgrade, I will
show you how to downgrade using snowbreeze.
