So one of my parents bought a new 3GS phone from Att. The first thing I did when she brought it home was to check which OS was running (4.3.3) and then I fire up tinny Umbrella. To my surprise, it said 4.1 and 4.3.3 saved :confused:

I asked my mom, if the phone was a refurbish. and She said no... or at least she though she was buying a new one.

Has anyone had that happen?
 
Sounds like the phone was refurbished. You can't transfer blobs from one phone to another. If you could, we wouldn't have to save blobs in the first place.
 
There have been isolated incidents where people seemed to be able to successfully request old SHSH blobs and actually get them. This may be the case for you, since there were a lot of firmwares between 4.1 and 4.3.3, and you would think at least one of those middle firmwares would've saved.
 
FYI, for a while cydia was having issues auto-saving blobs. I never did hear what the issue was, but it was around the time of those missing blobs.

What is an SHSH Blob anyway?

SHSH Blob Wiki


Or from the article:

An SHSH Blob (for Signature HaSH) is a 1024 bit RSA signature used to verify the validity of firmware on newer (iPhone 3GS or iPod Touch 2G onward) Apple iOS devices.
SHSH Blobs are used in a challenge-response authentication of the firmware, where the challenge key comes in a combination of a hash of the firmware and the Exclusive Chip ID (ECID) of the device. The response from Apple is the SHSH itself, the digital signature required to validate the firmware.
