Basic to Advanced Pre-Jailbreaking Questions iP4 iOS4.1
Very kind of basic question, I've been looking through a lot of guides and tutorials and would just like a straight up answer as to how to get to jailbreak and back (just to be safe).
First question is about backing my iP4(iOS 4.1) before starting jailbreak. Do I just use the back up feature on Itunes or should I use some programs like TinyUmbrella or such for backup before jailbreak.
I'm going to be using GreenPois0n method of Jailbreak, that part of it is easy
Second question is if I want to UN-Jailbreak my iP4 is all I do is use the 'Restore' feature in Itunes.
Third question is if I wanted to Unlock my iP4 in a year or so will that be possible.
Fourth question is what happens when Apple releases iOS 4.2? Will my iP4 stay Jailbroken? Will I have to do anything special or will I have to stay in 4.1 land??
Bonus question: after jailbreaking my iP4 when I plug it into iTunes can I do everything the same as I am right now with a non-jailbroken iP4? Like sync (it does auto back-up is that ok or will I loose my chance to restore my iP4??)

Are you sure that it completely wipes and reloads everything? When I did a full restore of 4.1, then jailbroke it later once Limerain was released, my previous 4.0 jailbreak data was still on the phone (the /stash folder contained duplicates of my jailbreak Applications, Wallpapers, Themes folders, etc). Seems strange if it was the iTunes backup that restored that specific data.
Awesome thank you very much farbod21, this is my first time Jailbreaking, I usually like to know what I'm getting into before I go all in.
One more thing I thought I read somewhere that somehow or sometime (maybe they haven't figured it out yet?) that you could Jailbreak your iPhone and could never be UN-Jailbroken and the only way Apple could fix this is with future new hardware iPhones upgrades. Cause all this Jailbreaking... updating, loosing the jailbreak, waiting for new jailbreak... repeat is just blaa.. or is that just the way life is? lol

The current jailbreaks, both Limera1n and Greenpois0n, use a hardware exploit that Apple cannot patch with a firmware update. So you don't have to worry about not being able to jailbreak your phone after a firmware update. But you will have to re-jailbreak if you update. So, until new hardware comes out, you won't have to worry about the "waiting for new jailbreak" part in your list.

The way apple firmwares work is that they wipe the slate clean and reinstall everything from scratch, which is why you always have to restore your settings and resync your phone after an upgrade. This works the same for a JB. You will always have to redo the jailbreak after every upgrade. There is no way around that.
