    I have an iPhone 4 on 4.2.1 that I need to upgrade to iOS 6 < 6.1.3 - is that possible?

    If you have SHSH blobs saved for whatever version you're trying to upgrade to, then yes.

    If you don't have SHSH blobs, then no.

    You have to read other post before you start posting.. everyone has asked this question and most answers are "no". Apple isn't signing iOS 6.
