On this website, you can monitor the changes in the signing of all iOS versions for all devices, including iPad, iPod Touch and iPhone. Once an iOS version has been unsigned, it’s not possible to downgrade or upgrade to it anymore unless you have saved SHSH2 blobs while it was still signed, SEP and Baseband are compatible, and there’s a way to set a Nonce Generator on the version you’re currently running. Once a new iOs version is released by Apple, the previous 1-2 versions may stay signed for a few more days or weeks before getting unsigned. This is to prevent users from freely downgrading to older iOS versions and jailbreak.
