So what if you are on 4.1 and never saved SHSH files for 4.0.1? Can you download 4.0.1 and load that through Tiny Umbrella and JB 4.0.1?
iPhone 5S - 64GB Space Grey
iPad Mini - 32GB Black
Apple TV 2nd Gen
MacBook Pro - 250GB Aluminum Unibody
Its always a good idea to save your SHSH with TU whenever a new firmware is released and signed. You never know if you will need it and it takes 5 seconds of your time.
This can also be used to try new firmware or beta versions of firmware without worry of losing your JB for long periods of time.
As an added bonus, you can even use TU to upgrade your iPhone4 to iOS 4.1 and try it out without updating your baseband (rendering your unlock obsolete). You do this by using the restore method described above for 4.1 with the 4.1 SHSH blobs saved. (iPhone4 ONLY as the validation used by the device is different than previous models)

I'm sure this has been covered already, just couldn't find an answer. To downgrade, do I need MY specific back-up/SHSH? Or for example, could you use someone else's file?
(Like the ones I used to Jailbreak/Unlock my 2G)

SHSH and .ipsw files are different things. What you used on your 2G sounds like a custom .ipsw. SHSH, which are unique to each phone, weren't used until the 3GS came out.
So—if you need SHSH, they do have to be yours.

I noticed tonight that the Cydia app has stopped reporting at the top of the screen which blobs it has saved on their server. It used to say SHSH blobs for iOS 4.01, 4.02 saved, or something like that, and now that is not displayed. Same thing for my iPad.
Is this a problem? When did this change?

My iPad is ALREADY JAILBROKEN. But on the Cydia page, I saw the prompt for "Make my life easier" but I accidentally hit the option: "I hate jailbreaking. Go away"!!!! Now the prompt is no longer there to save my SHSH!
I keep reading to use TinyUmbrella to locally save my SHSH. HOWEVER, can I still do this even though my iPad is already Jailbroken?!

here's my question...
im getting an iphone 4 in a few days and it will be locked. im planning on moving to another country in a few months so i'll need to unlock it. but i dont need to unlock it now... what will i need to do now to ensure me being able to unlock?
i dont care about jailbreak either at this point i would like to run 4.2.1 or at least 4.1, is that possible?
to make my question more specific (if i actually understand this whole baseband game right) if i get an iphone 4 and say it runs 4.0 with baseband 1.5 ( or whatever it is thats unlockable ) when i save SHSH files, then upgrade to 4.2.1 my baseband will get upgraded as well..
using those SHSH saves, can i restore back to 4.0 and the original baseband? or do basebands only upgrade but never downgrade? and once i upgrade i'll have to wait for an unlock for that baseband.
also, is there a way to upgrade to 4.2.1 but preserve the baseband for unlocking?
