I have a question, will I be able to downgrade to downgrade my iPhone 3GS (new bootrom, running iOS 4.1, 2009 model, A1303) to iPhone OS 3.1.3 without SHSH Blobs? If I am, will I be able to downgrade UNTETHERED? If so, how? Will sn0wbreeze work?
Thank you!

NOTE: I am only trying to do this for testing purposes.
