Downgrade from iOS 5 to 4.3.5 or others

Hi

Is it possible to to downgrade my iPod Touch 4G from iOS5 to 4.3.5? (or basically anything that isn't 5)
I'm running on Windows 7 and my device has never been jailbroken before. I'm seeking a downgrade because some apps aren't compatible with iOS 5 and I don't think the developers are updating it anytime soon. ):

Did you save any of you shsh's with tiny umberalla?

Unfortunately, no.
I've never heard about SHSH/Tiny Umbrella until I started looking around for solutions to my situation. I don't mind if I have to wipe out everything to downgrade it.

Well you need SHSH blobs in order to downgrade to that firmware.
