How to retrieve shsh files from cydia for iphone 3gs

I bought a Jailbroken and unlocked iphone 3gs running fw 4.01.
So I was trying to save my shsh files with tiny umbrella, and since it's fw 4.01, it says I'm too late. So what happens if something goes wrong with my phone and have to restore it? Would I have to go to fw 4.1 which would break my unlock? Thanks for all replies.

You can only save hashes for the firmware version Apple is currently signing, right now that is 4.1, too late for the others, so you cannot restore to anything other than 4.1

yes, you can save your shsh for whatever the current firmware is, because apple will sign it.

I believe you can use pwnage tool to update to 4.1 without baseband update, but as I do not have a 3GS or a reason to do this, I don't really know much about it.

Edit: (from the iphone dev site)

"PwnageTool allows you to restore to a custom IPSW file. For instance, you can restore to a pre-jailbroken firmware while simultaneously maintaining your current baseband (and thus your ultrasn0w carrier unlock). You can also add whatever packages you want in the “Expert” mode of PwnageTool, if you wish to pre-install Cydia packages. iPhone 3G users get the additional benefit of selecting their own boot and recovery logos, and features like multitasking and battery charge percentage."

Save your SHSH for 4.1 because that is all you can save for the moment. If you have to restore for any reason download a copy of 4.1 to your desktop and use pwnage tool to make a custom IPSW. This will enable you to restore to 4.1 and save your baseband for the unlock.
