Hey I had my 3G replaced under warranty thru apple like 2 days ago but it came with 3.1.2 and BB 05.11.07. So basically its a paper weight until dev team comes up with something. I was going to try to jailbreak it to see if is was a refurb that may have 5.08 BL so I could fuzzyband the baseband down. The problem is that everytime I try to jail break it via custom firmware I cant restore it thru itunes. It just says the file is not compatible. I know for a fact that it is b/c its the one my buddy uses on his. I have tried 5-6 different firmware customs and also tried to jb thru quickpwn which said the file was incompatible or corrupted.
Did apple change something that makes itunes not recognize custom firmware? Any help would be great ty!
