Possible to downgrade: iOS5 (b4) to 4.3.3

[kingoddball]

Hello!

I have an iPad 2 @ 4.3.3
Is it possible to install iOS beta4 (or newest) and then later reinstall/downgrade to iOS 4.3.3?

I do have the SHSH blobs for 4.*.*

I have seen it is possible on a few sites, but they do not seem reputable and they are based on older A4/iPhone/pod devices.
The iPad2 could be different. Safer to check

I am not 100% sute but do the beta 5 dont have a new baseband ? If so you can not downgrade because there is no baseband exploit

I have the wifi only model. No baseband.

Can you give a short instruction on how you did it? Just restored with iTunes?

And will it still work with the latest iTunes beta (running on 4.3.3)?

Do you have your blobs in TinyUmbrella or Cydia?

if cydia, change your hosts file to ask for the blobs in cydia and hold alt while restoring and chose your ipsw.

if you have your blobs saved in TU, start TinyUmbrella, start the server, and idk if u have to change ur hosts file

Tiny Umbrella updated today to support 3G iPads... I just went from iOS 5 beta 4 to 4.3.3 without a problem! I tried to do it this past weekend and it failed so something they did in the update today fixed the problem I was having!
