Hi I have a iPhone 5 which is on 6.1.3 yes I haven't update to the ios 7 yet. I am using a r sim so my carrier is unofficial. Anyways I was on my computer and I was on tiny umbrella. I clicked on save shsh blobs and it showed 6.1.2. This means my blobs are saved how can I downgrade without any problems. I would be grateful if you can help
