Will SHSH Blobs work with the iPhone 5?

Can I use shsh blobs with the iPhone 5 to downgrade it. I have iOS 6.1.4 and when iOS 7 comes out, I want to be able to downgrade just in case. Please list all the devices that can be downgraded with shsh blobs.

Only devices before the A5 chip (iPhone 4 and below, original iPad) can downgrade with SHSH. As soon as iOS 7 is released to the public and you install it, you won't be able to downgrade.

What you should do is try out iOS 7 now while it's in beta and see if you like it, since you can still downgrade to iOS 6 and stay there if you don't like iOS 7.To install the beta, you need to register your device's UDID with a developer account through a site like http://www.udid.in/.It's $5, and then you can try out the new OS before it comes out. That's how I got it on my 4S.
