i saved my 6.1.3 blobs a couple days ago right before i updated. even though i heard you cant downgrade from ios 7, figured doesnt hurt to save one. now im hearing that you can only downgrade only if you a.) have a A4 device and b.)have a shsh blob. so when i go to the blobs i saved when i was on 6.1.3, it has a 7.0 at the end of it, does anyone know why?
