i had the same issue and spazzed out, and finally called apple! they agreed to send me a new phone, but i decided to google "error 1013" and guess what i found a fix and it actually worked! if you on a pc (windows), click the "start" button! next , click the "programs" button! next click the "accessories" button! now either open up "notepad" or "wordpad"! i used "wordpad"! now go up to "file" and click "open"! now go to "c drive" and click "windows"! once you have "windows" opened, look for "system32" and click it! once that is open, look for "drivers" and click it! once that is open, look for "etc" and click it! it will probably be nothing in it! change file type to "all documents" and you should see a list of items! scroll down til you see "hosts", click it! you should see somethng like "gs.apple.com"! make sure that where ever you see "..gs.apple.com..", you put a # in front of it! now click save! now you should see a new "hosts"! i moved the original "hosts" to my desktop! also just to be extra safe i deleted "tiny umbrella"! then i went to itunes and my iphone 4 restored!!!! then i reinstalled "tiny umbrella"!
