If you saved your blob on saurik's server then yes. If no, then no.

If you have to ask, then you didn't.

If you dont have shsh's saved locally or on cydias server then you can only restore back to 4.0.2
You can check with Tinyumbrella, it will list if and what shsh firmware versions you have on file.
