    Depends what model of iPhone it is, if it's a 3GS what bootrom it is, what SHSH blobs it has saved etc.

    More information would be useful please.

    Check Cydia and see what SHSH are available. If it has 4.0 use TinyUmbrella TSS server to update to 4.0 then Jailbreak with Jailbreakme.

    If it's old bootrom, do a snowbreeze custom firmware upgrade.

    No you can't upgrade it to 4.0 without SHSH blobs.

    You could upgrade it to 4.1 if he doesn't need an unlock for it and jailbreak it with limera1n. But if he needs an unlock you can't.
