Hey guys, I noticed that someone successfully downgraded iOS 4.3.5 (tethered jailbreak) to iOS 4.3.3 for an untethered one. My question is can this procedure be followed to downgrade 5.0 as well.

Downgrade 4.3.5 to 4.3.3 without SHSH Blobs - iPhone 4, 3GS, iPod Touch 4G, 3G, iPad - Jailbreak 5.1 / 5.0.1 / 5 / 4.3.5 / 4.3.2 / 4.3.3 / 4.3.4 Untethered - iPad 2 Jailbreak

That's the guide for 4.3.5 to 4.3.3 without blobs. Now what I have imagined is pretty much the same, download the redsnow version that jailbreaks 5.0 point to 4.3.3 restore in iTunes using shift restore, point to 4.3.3 use tiny umbrella to remove it from recovery mode...

The above guide is more detailed, anyway anyone more experienced have any idea If it's worth trying? Or a reason why 5.0 would not work even tho 4.3.5 did?
