    I just jailbroke my iphone using Limera1n. If I want to upgrade my firmware from 4.1 to 4.2 (when it comes out), what do I do? Do I need to restore my phone and then jailbreak it again using the same method?

    I've saw Cydia will be upgrading to support OS 4.2 as well, what does that have to do with everything? I'd Really appreciate if you can post me some instructions!

    Thanks in advance.

    You have a few options to upgrading to the new update when it comes out.

    PwnageTool: allows you to upgrade to the newest update while preserving your baseband (so you can unlock)

    OR

    You can just upgrade via iTunes if you don't need the unlock.

    Cydia is just being updated so it can be compatible with the new 4.2 jailbreak.

    You wait till there's tools available and cydia packages updated to work with 4.2
    Right now u will be stuck with a tethered jb and probably not many jb apps will be compatible.
    That's the way the jb game is played. We usually gotta wait and don't update right away as soon as a new firmware is out.

    well at least wait till it comes out sides like Iclarified will then have a step by step tutorial. most Cydia apps will not support 3.2 from the get go. also you want to be careful about your baseband if you plan to unlock. I will probably wait about 2 weeks after 4.2 is released. I'm never 1st on the block I let others be the guinea pigs! ;)

    I haven't unlocked my phone only jailbreak it. I've heard if i just upgrade over itune, there's gonna be some problems.

    So should i restore to backup first and then jailbreak again?

    does Limera1n allow you to jailbreak version 4.2?

    Yes. LimeRa1n as stated by GeoHot jailbreaks 4.1 and higher.

    As long as you have a Mac you can use Pwnage. Yep, you keep your baseband by creating a custom ipsw file

    Pwnage is a jailbreak tool created by the iPhone Dev-Team: http://blog.iphone-dev.org/post/1359246784/20102010-event

    Before starting a new thread. You should go read some sites that will give you more information about PwnageTool. For instance, http://blog.iphone-dev.org/

    You don't even know PwnageTool is and what it does.

    I can't believe this guy got put down!?!?!

    gngan are you seriously that sad? "Steve Jobs" pwnage is pure ownage. I'm not so into that stuff as I am a developer. Too busy to focus on terms and putting people down. We all start somewhere. Open a thread if you think its worth it and if people think they are too advanced they should go away. In the IT world, there is SO MUCH to learn and know, knowledge becomes prehistoric quickly and you have to start somewhere.

    I only started with these things two yrs ago and am 30, the right people and learning the right questions is where you need to be. Here is the trick for the future. Google what you want and when you don't see it google different terms or identify words to include that are industry jargon. Most of us enthusiasts and developers have no time to explain what is already out there, BUT some of us have the time to make you feel stupid. Don't be deterred by tools and never stand down when someone puts you down. . coz the knowledge they have you can obtain and the heart you have, they will NEVER gain.
