This is step-by-step instructions on how to jailbreak and unlock your iPhone 3GS on iOS 4.2.1 firmware using RedSn0w 0.9.6b5 for Windows.

For iPhone 3G use this tutorial.

If you have an iPhone 3GS with the new bootrom you will only be able to perform a tethered jailbreak at this time. This means you will need Redsn0w’s assistance to boot into your jailbroken device.

IMPORTANT FOR UNLOCKERS
During this process you can update your baseband to the 06.15 version. If you are on 05.14 or 05.15 or higher you will need to do this to unlock. You do not need to do this for jailbreak only. Please read the following very carefully before deciding whether to do this.

These are instructions on how to jailbreak and unlock your iPhone 3G on iOS 4.2.1 using PwnageTool 4.1.3 for Mac OS X. This tutorial will explain how to upgrade your baseband if needed for an unlock.

Step One
Make a folder called “Pwnage” on the desktop. Download a couple of things:

• PwnageTool 4.1.3 from here

You will also need the 4.2.1 iPhone firmware.

• iPhone 3G iOS 4.2.1: iPhone1,2_4.2.1_8C148_Restore.ipsw

If you are on the 05.14 or 05.15 baseband you will also need the iPad 3.2.2 firmware. You can find out your baseband version in Settings -> General -> About -> Modem Firmware.

• iPad iOS 3.2.2: iPad1,1_3.2.2_7B500_Restore.ipsw

When downloading the IPSW file, it is best to download it with Firefox since Safari often auto extracts it!

Step Two
Double click to mount PwnageTool then drag the PwnageTool icon into the Pwnage folder.

DevTeam hacker MuscleNerd tweeted that they after releasing redsn0w jailbreak for 4.2 the team can start working on iPhone unlock. Users can expect the unlock for the iPhone 3G and iPhone 3GS this week. The iPhone 4 unlock will take more time and no concrete info is available about that yet.

The unlock will be released for iOS 4.1 firmware. So is you need unlock, do not update to iOS 4.2.1.

DevTeam worked hard for the last several hours and released jailbreak tool for iOS 4.2.1. It is redsn0w 0.9.6 b4.

As usual we remind all ultrasn0w unlockers please stay away from this official firmware. Wait for the ability to create custom 4.2.1 IPSWs that don’t update your baseband!

New redsn0w 0.9.6 b4 uses limera1n exploit and will successfully jailbreak all devices. The only problem is that it is a tethered jailbreak, which means you will have to plug it to a computer and rerun redsn0w on every reboot. This so called tethered or semi-tethered jailbreak. This condition applies to iPhone 3GS (new bootrom), iPhone 4, iPad, iPod touch 2G (MC model), iPod touch 3G and iPod touch 4G. Hackers are working hard to create untethered jailbreak for these devices. To use future untethered jailbreak you need to save SHSH keys for iOS 4.1 using TinyUmbrella utility or directly in Cydia.

Old devices like iPhone 3GS (old bootrom), iPhone 3G and iPod touch 2G (non-MC model) can be jailbroken-untethered right now using this latest version of RedSn0w.

You can download RedSn0w 0.9.6 b4 here.

The iPhone Dev-Team recently has released a new version of RedSn0w for Mac and Windows.  RedSn0w uses the Limera1n exploit to support more devices and adds the ability to restore custom firmware ipsws. The crew promises that now RedSn0w will work with the iPhone 3G, 3GS, 4, iPad, iPod 2G, 3G, and 4G (Not iPod 2G-MC yet).

You can download RedSn0w 0.9.6b2 from here.

Mike Pan has successfully modified his iPhone 3GS and now it can record HD video at 1080x800px with 30 frames per second and up to 20Mbps! The original ability of this handset is 640x480px at 3 Mbps. Mike used the non-standard resolution so the video could be kept at the right aspect ratio.

So here is a short instruction how to enable HD-video recording on your iPhone 3GS with firmware 4.1 (as other firmwares haven’t been tested yet):

1. Download HDVideo3GS.zip.
2. Jailbreak your device and install SSH.
3. Copy N88AP.plist to /System/Library/CoreServices/SpringBoard.app/
4. Copy the 3 other plist-files to /System/Library/PrivateFrameworks/Celestial.framework/N88/
5. Reboot your iPhone 3GS

Some features:

• Low light capability cannot be enhanced, so dark areas will still have grains.
• In case you want to send the recorded HD-video to YouTube in its original quality, use Pixelpipe from the App Store.
• The maximum shutter duration has been increased so now you can take photos even in dark areas, but a steady surface or tripod is highly recommended.

Mike promises to release an app in cydia so that the procedure could be even simpler. For those who’d like to understand how he did it, he posted a detailed instruction here.
