Questions for jailbreaking in general

[misfiringsystem]

I can't find an answer to these so I thought I asked here.

1. Do I need to be on the latest firmware from Apple to jailbreak the iPhone? ie, I need to upgrade my iPhone to 4.1 before I use the jailbreak software that is currently available from hackers.

2. What's the difference between limera1n, sn0wbreeze, and tinyumbrella? Don't they all perform the same function, jailbreak the iPhone?

Thanks

limera1n" is jailbreaking program...You can JB 4.1 firmware with it..
sn0wbreeze" is unlocking program that let you to chose which phone carrier you want to use
tinyumbrella" is the program that saves your firmware with all apps on it so you could easily downgrade your Iphone..
And yes.. you better be on 4.1 to JB with 'limera1n'

Yes limera1n is a jailbreaking tool. It allows you to jailbreak the phone in the state its already in, without loosing anything.
Sn0wbreeze is a tool that allows you to create custom IPSW files (the actual iphone os software).
Tinyumbrella is a tool that allows you to downgrade your iphone to an earlier os depending on whether you have what are calle shsh blobs saved on either the cydia server, or locally on your computer.
I realise i may have just created more questions for you in this reply, so if u would like them answered, and or some advice, please pm me or ask on this thread

1. So from what I gather, if I'm on 4.0.2 right now and haven't jailbroke yet, I need to update to 4.1 before I can jailbreak?

I don't know if this list is right, but from what I gather

pwnage tool - allows users to update and preserve baseband
requirements: on MAC only

sn0wbreeze - windows version of pwnage tool
requirements: iPhone - iPhone 3GS, must be jailbroken beforehand?

tinyumbrella - sn0wbreeze for iPhone 4?

you do not need sn0wbreeze to use tinyumbrella

[ukhellfire]

First off... Are u on a mac or pc??
Tinyumbrella does not jailbreak at all.
Are you in need of unlocking your iphone in order to use a different service provider??
If you are on a pc and dont need to unlock, i would recommend doing a full backup through itunes, and then upgrade to 4.1. Again through itunes. Once upgraded, do a restore from the backup u creates jst now. Then download limera1n from limera1n.com and follow the onscreen instructions in the program. This will successfully jailbreak your phone. Then once the phonenboots back up, you should have a new app called limera1n. Open that, install cydia, and your done! Fully jailbroken!!!

Problem is, the phone has never been jailbroken before.

If I update to 4.1, then I will also update my baseband, losing my opportunity to unlock for quite a while.

I can't find any programs that allow me to upgrade to 4.1 on my 3GS and preserve my baseband.

However, I want to jailbreak 4.0.2, and there doesn't seem to be a program anymore to do that?

[j3st3r]

limera1n will jailbreak 4.0.2

[misfiringsystem]

That means I've screwed up my jailbreak

Side question, is there any way to restore an iPhone to factory settings WITHOUT going through an update?

Long story short, I've bought a used iPhone and I want to restore it to factory settings. But restoring it would also mean updating it to the latest firmware and baseband.

[j3st3r]

not that I'm aware of
