Hello. First of all, if you want to downgrade, your phone will
need to be jailbroken. After your phone is jailbroken, you will
be able to back up your shsh blobs. SHSH blobs are basically
apple's way of signing firmware, and also their way of preventing
users from downgrading. Apple is so against users jailbreaking
their phones, that they will force you to use the latest version
of IOS.
After your phone is jailbroken, it is easy to back up your
shsh blobs. You can either use a program like Tiny Umbrella, or
you can use a utility called ishshit to back up your shsh blobs
right from your phone. I'm not going to post downgrade
instructions at this point, because I don't know if your phone is
jailbroken. If you want more information on how to jailbreak or
downgrade, let me know.

Subject: How to downgrade to IOS 5.1.1
Hi list,
about a week ago or so people have just mentioned that it is
possible to
downgrade to IOS5.1.1 in case someone doesn't likeIOS6.
It is not my situation since I haven't upgrade my Iphone 4 to
IOS6 yet
but I think I will try and upgrade tomorrow.
Please would you be so kind to give me step-by-step instructions
how to
downgrade to IOS5.1.1. I am asking for this just in case I do
not like
new IOS or have some bugs.
Thank you in advance for your help. It will be very highly
appreciated.
With kind regards
Maria
