4.3.5 problem

[mrporridge]

Hi
I'm new to the jailbreak world.

I've got iphone4. on version 4.3.5
I DO NOT have 4.3.3 SHSH blobs.
I only got introduced to the world of jailbreaking post upgrade.

I have saved my 4.3.5 SHSH blobs on tinyUmb. When I try to 'downgrade" to 4.3.3, my itunes does not allow me (I go into recovery and need tinyUmb to sort me out)

1) am i able to downgrade if I don't have 4.3.3 blobs saved?
2) is a tethered break my only solution?
3) if I go the tethered break, am i tethered for life, or if a subsequent version, ie iOS5, is untetherable, will I be able to upgrade to that, to get an untethered brk.
4) if I have to settle for a tethered break, is redsnow the best software to use

Thanks for any help (sorry for so many quetsions)

1) unfortunately you cannot downgrade.
2) at the moment a tethered jailbreak is your only option
3) hopefully you won't be tethered for life. I'm sure as soon iOS 5 is released an untethered jailbreak wont be too far behind
4) I would recommend you use redsn0w

Can I dg 4.3.5 to 4.3.3 , they have same BB and I saved SHSH on TU & Cydia.
Everytime I've tried ip4 gets stuck with error 20? I don't think I have the DFU step
the right way.
