So I want to try the voltage thing. Now i got a question. In the 'readme' it says to place the 2.1.1 FW in the 'jb_files' folder. In the actual program it tells me to put it here- C:\Documents and Settings\Justan Jr\Local Settings\Temp\Rar$EX00.765\JB_Files As far as i can see, i dont have the above^...i cant seem to find it. Where should i put the 2.1.1 FW? Also, under requirements it says 2.2.1 IPSW. Is that what firmware i need to be on BEFORE i jailbreak or do i need that one downloaded? Either way, im on 2.2.1 and have it downloaded already so it doesnt really matter, just want to clarify that. Thanks, Justan PS-Has anyone had success without downloading C++?
