Iphone 4 4.3.3 update and restore backup on iOS 5 B4 question?
 

Hello,

I have 2 questions. I'm currently on iOS 4.3.3 (iPhone 4) and would like to update to iOS 5.0 beta 4 firmware and jailbreak it with redsn0w 0.9.8b4 for testing out new features..

1.) Can I restore my saved backup from iOS 4.3.3 on iOS 5.0 BETA 4 or the backup isn't compatible with the iOS 5.0 beta backup format?

2.) Can I downgrade later normally from DFU mode back to 4.3.3 or TinyUmbrella is needed aswell?

Please answer only if you already tried above

Thanks in advance!
