    Hello out there

    I have successfully JB my 3G with 4.1 and RedSn0w.

    But i want to upgrade to 4.2.1 again with RedSn0w. I have downloaded everything, but im just worried about, that the iOS version im trying to download thru iTunes is 4.2!

    I cant run the cracked iOS that i downloaded with redsn0w in iTunes.

    Can i simply just install 4.2, and then use the 4.2.1 JB ??

    Thank you !!

    4.2 isn't being signed anymore, so you can only restore to 4.2.1
