    First let me apologize for this thread as I know for a fact there must be a bunch like it, but I'm browsing from my iPhone and everytime I try to search I get the "Safari could not connect to the server" (paraphrase, but I'm sure you know the one) popup message. It's driving me nuts, and I hate to create a thread on a topic I know has been covered before, but I'm at work and don't have time to browse through pages and pages of forum threads. I'm assuming they're pretty far back as 3.1.2 has been out for awhile. So anyway, sorry for the repeat thread, and probably the length of this post. Here goes:

    Right now I'm using a launch day 3GS with 3.0 FW, jailbroken with PurpleRa1n (and a PC with Windows XP). It's been great and I've never really felt the need to upgrade to 3.1.x FWs as MMS wasn't THAT big of a deal to make me have to re-setup all my JB settings. However now I'm running into the problem of a lot of the newer apps I want require 3.1.x FW. The Grand Theft Auto: Chinatown game, that speech-to-text app, and Conan O'Brien's "Walker Lever" (lollol) being examples. So I finally decided to just upgrade and re-JB. I'd like to use BlackRa1n, as PurpleRa1n was ridiculously easy and quick so Im basically looking for a tutorial (or link to an existing thread) that gives me step-by-step info and answers the following questions:

    1 - Do I just upgrade to 3.1.2 via iTunes when it asks me to (everytime I connect my phone to my PC lol), or do I need to get a custom 3.1.2 FW and upgrade to that (I believe using the shift + something else method to select that file in iTunes correct?)? If so, where can I find that custom FW file?

    2 - Are all versions of iTunes compatible with 3.1.2 JB? I remember reading something here awhile ago about NOT upgrading to the newest iTunes if you had a JB phone, is that still the case? I'm running an older iTunes now, but I'm not sure which version, I just looked up a version of iTunes released around the same time as the 3GS and got that, because that is the version that installed on my other computer when I first setup my new phone.

    3 - Once I'm upgraded to 3.1.2 is BlackRa1n just like PurpleRa1n, just DL the file, plug in your phone, and double click BlackRa1n to "make it rain"?

    4 - I'm running Categories right now, do I need to remove all apps from that before upgrading to 3.1.2?

    5 - does all the good stuff work with 3.1.2? Roatation Lock, the other SBSettings, Categories, Stack, Winterboard, etc?

    6 - Any other important info/tips I should know?

    Thanks again, I always come here for info on this stuff because the community here is so helpful and knowledgeable and for the most part friendly. It's a place you feel like you can ask for help (or create a thread about a topic that's been covered already, lol, sorry) and actually recieve legit, helpful answers instead if being bashed or talked down to etc like a lot of other iPhone-modding forums, or just forums in general.

    If you are going to use blackra1n, yes. But I would strongly urge you to use PwnageTool/custom firmware instead. You have the 04.26.08 modem firmware (baseband) on your phone, which means it can be unlocked using ultrasn0w. If you upgrade to the official firmware, you will upgrade your baseband and will lose the ability to unlock using ultrasn0w. While you may not need to unlock yourself, your phone will be much more valuable for resale if you preserve your baseband.

    2 - Are all versions of iTunes compatible with 3.1.2 JB?

    You're safe to upgrade to the latest version of iTunes.

    3 - Once I'm upgraded to 3.1.2 is BlackRa1n just like PurpleRa1n, just DL the file, plug in your phone, and double click BlackRa1n to "make it rain"?

    Yes, blackra1n is still ridiculously simple. If you do choose to go the upgrade-then-jailbreak route, though, I would recommend redsn0w over blackra1n. I've heard of far fewer issues with the redsn0w jailbreak than with blackra1n.

    4 - I'm running Categories right now, do I need to remove all apps from that before upgrading to 3.1.2?

    Upgrading will delete all your Cydia apps anyway, so you do not need to worry. I would recommend buying PkgBackup from the Cydia store to backup your jailbreak setup before upgrading.

    5 - does all the good stuff work with 3.1.2? Roatation Lock, the other SBSettings, Categories, Stack, Winterboard, etc?

    Yes.

    6 - Any other important info/tips I should know?

    If you use the Ben.M tethering hack, be aware that you will need to patch commcenter to remove the mobileconfig signature check added in 3.1. There are lots of threads on enabling tethering in 3.1.2.

    Wow, awesome info, thanks so much. I wasn't planning on selling my phone, but I think I might do the method you described just in case. Better to have my original baseband and not resell than to decide later I want to resell and not have it.

    Do you have a good guide to creating the custom FE file and Doing the jailbreak method you suggested?

    Having an unlocked phone generally increases the value by $100.

    Indeed. And I imagine an iPhone 3GS with the old iBoot and an ultrasn0w unlock will be worth most of all.

    If you do not have a Mac, you will need to find one already created online. Please don't ask here; we can't post links to copyrighted materials. You will be looking for a file called iPhone1,2_3.1.2_7D11_Custom_Restore.ipsw. Make sure you get one that is not hacktivated if you are on AT&T.

    Since you have a 3GS, I think he meant to type "iPhone2,1_3.1.2_7D11_Custom_Restore.ipsw"

    It's 2,1 not 1,2
