3.1.3 to 4.0.1

[BumbleBeez]

I have a 3G[S] running 3.1.3 Spirit Jailbroken.

I have SHSH on file for 3.1.3, 4.0, 4.0.1 and 4.1 (no idea why I don't have 4.0.2, but that one doesn't matter anyway).

I just recently upgraded to iTunes10. I have Tiny Umbrella. I do not need an unlock.

Since I see greenpois0n is only going to be for 4th gen devices, and that's what I have been waiting for, I guess it's time for me to upgrade to 4.0.1. I'm tired of seeing "you must have 4.0" when go to purchase apps

So, I plug in my phone, start Tiny Umbrealla, Start the TSS server. Restart iTunes. Shift-click and select the 4.0.1 firmware ... and let it work it's magic?

Does the phone need to be in DFU mode for the 3.1.3 upgrade? Or is that only for a downgrade?

Then just jailbreakme.com!

Anything I am missing??
