Why don't you just tell us if it says you have a 4.3.3 SHSH saved or not? That's all we need to know.
Unfortunately you cannot restore 4.3.3 then. If you're on 4.3.3 right now, you can still dump your 4.3.3 SHSH using iFaith, but that's your only option.
I did dump shsh using iFaith on our son's pc laptop.
I'm wanting to restore my 4.3.3 device cause of battery issues. Am I able to restore my device as new and keep 4.3.3 since I dumped shsh using iFaith? My iPhone is configured to a Mac does it matter if I dumped shsh using iFaith on a PC?

Good, so you should now be able to use iFaith to help you build a pre-signed 4.3.3 firmware for your Phone and help you install it using iTunes.
Make sure you backup by syncing with iTunes first if you want to restore your settings from backup once the firmware restore is complete.
Well, the first option you get when you open iFaith is to "build a signed IPSW w/blobs", so you could try that
