    Sorry if this is really common but I'm just a bit lost with all the tools for the different purposes!

    I currently have a 3GS on jailbroken 3.1.2 [using Blackra1n], is there a way I can upgrade to 4.0 and jailbreak it as well?

    Windows-only solutions right now unfortunately :rolleyes:

    Thanks! :)

    Download a pre-pwned firmware created by someone who has a Mac and restore to it.

    Only if you have the old bootrom.

    I apologize for my newbiness, but is there somewhere public I can get the pre-pwned firmware?

    Yes I have the old bootrom. :)
