I did a search but am not sure if I phrased my search correctly, so apologies in advance if there is an easy answer for this. Basically, I'm on 4.0.1 JB and I have my SHSH blobs from 3.1.3 all the way up using Saurik's method. But, I need to take my phone in to Apple to see if they will replace it. But if they don't (since it's out of warranty), I'd like to stay on a lower iOS version, like 4.3.3, if possible. Since it's been over a year since my JB, I just can't remember the details. I'm guessing that I should download an older firmware, and then do a shift (or alt) restore in iTunes. Now my question: If I do this, will I be able to take it in to the Apple Store as a clean/non-jb phone, or do I need to just do a clean restore and upgrade?
