    Hi guys,
    I'm running 4.0.1 on my 3GS (jailbroken my jailbreakme) and I am wanting to upgrade to 4.1.

    Now I've been hearing about SHSH and downloading firmwares, but is this necessary if I don't need my phone unlocked? I am using Telus (which is a carrier in Canada that has iPhones), so I do not need to unlock to another carrier. I have read that I should do the SHSH with Tiny Umbrella before restoring if I don't want to upgrade my baseband, but is baseband important if you don't have an unlocked phone?

    I'm thinking I can just restore on Itunes, download 4.1, restore from backup, then do Limer4in or greenp0ison.

    Thanks, clarification would be appreciated.

    The SHSH has nothing to do with unlocking, it has to do with jailbreaking. If you screw up (and from your obvious refusal to research, it's likely you will), you'll need the SHSH.
