Jailbreak iPhone, iPod Touch, iPad

MuscleNerd has recently announced via tweeter that ultrasn0w unlock for iPhone is now fully working on iOS 4.2.1

Finally got ultrasn0w working fully on 4.2.1. Apple inadvertently(!) broke ultrasn0w via aggressive compiler optimization

MuscleNerd previously announced that the ultrasn0w unlock should be available by Sunday for the iPhone 3G and iPhone 3GS. The unlock for the iPhone 4 will take much more time.

UPDATE: this is not a reason for update to iOS 4.2.1, wait for utilities.

In iPad OS 4.2 ‘Orientation Lock’ was changed to ‘Mute Switch’. If you want to change it back there is an app for that.

NoMute, a jailbreak only application, switches the controversial mute switch from iPad 4.2 into its former (and more useful) orientation lock. The plugin is free and you can get it from the BigBoss repository on Cydia.

By the way you can lock screen orientation without jailbreaking through multitasking panel – just push Home button twice, slide to the left and hit lock icon.

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.

Next iPhone/iPod/iPad firmare iOS 4.2 is due out soon. What can we expect in terms of jailbreaking 4.2?

Limera1n exploit for 4.2 in most cases is a tethered jailbreak. That means if you have to reboot your device, it will show a “connect to itunes” logo until you run the jailbreak software again.

• iPhone 3G – will run 4.2 untethered. Redsn0w will be updated.
• iPhone 3GS – old bootrom will run 4.2 untethered if done via Pwnagetool while updating from 4.1. Otherwise it will be tethered.
• iPhone 4 – tethered
• iPod 2G – untethered.
• iPod Touch 3G, iPod Touch 4G – tethered
• iPad – tethered.

Tethered jailbreak isn’t that bad for iPads and iPods. But if something happens and your iphone reboots while you’re away from your computer, you cant use the device until you get home and run some tool on your computer again.

We suggest not updating until new expoit will be implemented in new utility.

The community is working on a solution to this to either make the jailbreak untethered or at least semi-tethered. Semi-tethered means the device will at least reboot, but unjailbroken while on the road until you return to your computer.

Multiple developers and users testing out the iOS 4.2 betas claim that the AirPlay functionality was definitely removed from Apple’s iPhone 3G. AirPlay is gone from the golden master version of iOS 4.2. In fact, the AirPlay did work on the iPhone 3G at the previous betas. There are no any reasonable causes why the AirPlay was cut from the GM version.  Perhaps, Apple is trying to get users to upgrade to their latest iPhone model or, on the other hand, it is just an issue in the GM seed. May be the AirPlay functionality will return in iOS 4.2 public release. Anyway, there will undoubtedly be a jailbreak that can re-enable it.

MobileTerminal is a terminal emulator application for the iPad and iPhone. The version of MobileTerminal that is available in Cydia doesn’t work with iPhone iOS 4.x. However there are beta versions that do work, but aren’t on Cydia because they are still in beta stages. This tutorial will show you step-by-step how to install MobileTerminal on iPhone with iOS 4.x (tutorial for iPad is here). If you have old version of MobileTerminal installed – uninstall it in Cydia (Search – MobileTerminal – Remove).

First of all you need to jailbreak your iPhone. If you have not done it already here is an easy tutorial: how to jailbreak iOS 4.0-4.1 on iPhone using Limera1n. After you successfully jailbreaked iPhone:

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.

It seams that hackers have had their hands on the iOS 4.2 beta 3 for iPad. But, as we know, there is no official jailbreak for it. Recently the well-known iOS hacker posted aт interesting picture in Tweeter. The shot depicts an iPad running MobileTerminal, a jailbreak application, which gives users full access to the terminal command line interface. But it looks strange, because it means that the hackers missed the beta 4, which should be released this past Tuesday, according to the Apple’s schedule. This could signal that Apple may skip beta 4 altogether and go straight to a GM build sometime next week.

These are instructions on how to jailbreak your iPhone using PwnageTool 4.1 for Mac OS X. If you need unlock and you have not updated to iOS 4 you will be able to preserve baseband and unlock iPhone using ultrasn0w.

This guide will work for iPhone 4, iPhone 3GS, iPhone 3G, iPod Touch 3G, iPod Touch 4G, iPad and AppleTV. Just use the right firmware and select the right device (step four).

Step One
Make a folder called “Pwnage” on the desktop. Now you need to download there PwnageTool 4.1 from here and iOS 4.1 firmware from here.

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.
