A bit of a problem here... After getting a bit anxious, I downloaded iOS5, not realizing I needed a UDID, which I do not have. After realizing this, I want to put my CDMA iPhone back to the way it was before. I put my iPhone in DFU mode, but when I option click restore, and click my 4.2.10.ipsw, itunes gives me an error (I think 1015). After searching the internet for hours looking for a solution, Either nothing has worked, or I have gotten multiple errors. I was using 10.5 beta before, but I saw something that said try it in 10.4.1, which doesn't work either. Thanks!
