    I have a 3g with 3.1.2 firmware. According to the flowchart, in the sticky, i want to upgrade, to 4.0 and jb with redsnow.

    when plugged in itunes asks me if i want to upgrade to 4.1

    I am assuming that i want to upgrade to 4.1, the downgrade to 4.0 in dfu mode. then jail break? Is 4.0 the best firmware to use, with a jb device?

    I would just like to ask first being the amount of information out there is tremendous, and easy to get lost in.

    Edit: I clarified's instructions mention using blacksnow. So i guess thats what i would go with.

    4.1 is current firmware, so without hashes saved, you can only go to 4.1. If you have hashes saved for other firmware versions, you can install those.

    If you install 4.1 you get a new unlockable baseband (but there is an unlock ready, will be released after Apple releases 4.2 firmware)

    A 3G on 4.x.x firmware will be slow... you can turn off wallpapers, multi-tasking and spotlight searches to speed it up but, it has too little ram and too slow a processor to run very fast.
