So, I bought a iPhone 3G. The problem is, im not sure what firmware was on the thing, because when i got it it just had the famous "waiting for activation" screen. I tried Blacra1n, But nothing. I tried restoring, to both 3.1.2 and 3.1.3. I'm just getting error codes 1600 and 9. I've put it into DFU MULTIPLE times, and tried restoring normally. Any suggestions? Thanks in advance!
