How to unlock and jailbreak iPhone 4 with redsn0w?

[ThE.MeSsEnGeR]

I'm right now on a 1st gen. iPhone (8GB) running on iOS 3.1.3 (well, it was still called iPhone OS )

tomorrow I'll be getting a new iPhone 4 (32GB), that will be running on iOS 4.1
I already downloaded the IPSW of 4.3.3 and redsn0w 0.9.6rc16
because as soon as I get it I want to update it to 4.3.3 and then I want to unlock it and jailbreak it.

now, can I update it normally from 4.1 to 4.3.3 before even jb'ing it? and is it straight forward when using redsn0w? or do I need to watch out for something?
I know NOTHING about basebands! I'm afraid I might brick it...

please, I would appreciate any help,
Thank you!

switching from a
8GB iPhone running 3.1.3
to a
32GB iPhone 4 running 4.3.3

(and in just 3 months will be on iOS 5).... how drastic will THAT be?!

you can jailbreak no probs with redsnow
cant unlock iphone 4 tho.

only baseband that was unlockable was 4.0 and 4.0.1

I'm sure that iPhone 4's can be unlocked later than 4.0.1

I'm no unlocking expert, but from what I understand, 4.1 and beyond probably upgrade the baseband. Only early iPhone 4's that shipped with 4.0.1 or earlier have a baseband that is currently unlock-able.

so, if the iPhone that I get is already on 4.1?? will I be screwed???
please, PLEASE, tell me no...


[EDIT] and if redsn0w doesn't work, do you think I can do something with PwnageTool??

Pwnage Tool is for advanced jailbreakers only, use redsn0w rc17 and it will work

For any info look this up:

you're talking about jailbreaking, I know that it can be JB'ed... but what I want is to unlock it to use it here in Lebanon...

anyway, after THREE long, tiring hours of research and reading... I finally came to the conclusion that I'm one of the late people to get on the Gevey train...

so, I found out that Gevey Turbo SIM is my one and ONLY solution to unlock my iPhone 4.

should I jailbreak before or after I do Gevey's process? should I do that process everytime I turn off/reset my iPhone? what about when I lose service?

will I lose any functionality or call quality??
