Hello all, I've recently purchased an Iphone 4 that comes preloaded with the 4.02 OS. This is my first iphone ever. I want to jailbreak my phone, so what i need to do is to downgrade my OS from 4.02 to 4.01. Using TinyUmbrella, under advance option on the request version field, which version should i be choosing in order to first save my SHSH Blob? 4.1, 4.02 or 4.01 Thank you very much.
