Unlocking iPhone4 4.3.3

[germanguy]

Sorry if this has been asked before. Am I able to go on my iphone 4 from version 4.1 to 4.3.3 using tinyUmbrella to maintain baseband and unlock it with Ultrasn0w. iClarified only has instruction to do this up to version 4.3.1

What current BB does it have now?

assuming you have 1.59 yes you can update to 4.3.3 and keep the baseband http://www.iclarified.com/entry/index.php?enid=12134 and a few other links. if you have any other baseband then it doesn't matter there is no unlock.

If you're in official 4.1 then the bb cannot be unlocked.
If you have anything higher than 01.59.00 modem firmware your sol.

If you've got 4.1 firmware and you've never preserved your baseband before, there's no point in starting now. You most likely have 2.10 baseband (or something like that, I don't actually own an iP4) and that baseband is useless.

Yes. I have baseband 1.59. Had preserved it previously. Thanks for the responses.

You're good then.
Make sure you don't screw it up.
