iPhone 4 - Is Apple still signing 4.3.3 original firmware?

[Studie]

Is apple still signing original firmware for 4.3.3?

Or will I have to restore to my custom image of 4.3.3?

Thanks!

Apple is only signing 4.3.5 right now (unless you have a 3GS in which case Apple is still signing 4.1 as well). You need SHSH for the firmware you are restoring to regardless of if it is stock or custom.
