So today i was trying to upgrade my iphone from 3.1.3 to ios 4 and i keep getting the 3194 error. I have my shsh files saved and i've done some searching but I seem to only find help on how to downgrade from 4 to 3.1.3. i didn't think i'd have trouble trying to upgrade. So can someone please help me out and tell me how to upgrade to 4.0 or 4.0.1 and i checked with tinyumbrella and I do my blobs for both.
