Jailbreak iPhone, iPod Touch, iPad

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.

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.

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.

PwnageTool screen about to get a lot more crowded again due to limera1n exploit http://is.gd/g7P9G (unlockers win most)

New PwnageTool was expected to be released last weekend, however it was delayed.

- iPad (iOS 3.2.2)

Greenpois0n uses that same exploit as limera1n.

You can download GreenPois0n from here.

In addition to our LimeRa1n jailbreak tutorials, here is a nice video showing all the process:

LimeRa1n supports iPhone 3GS, iPhone 4, iPod Touch 3G and iPod Touch 4G with iOS 4.0 -- iOS 4.1, and iPad with iOS 3.2.2.

Use the same steps to jailbreak iPod Touch 4G and iPod Touch 3G and even iPad. You can find the Windows version of this tutorial here.

Remember: Do not update to iOS 4.1 if you need the unlock. Ultrasn0w does not support that baseband yet.

Press both the power and the home buttons.

When Limera1n asks you to, release the power button.

Your phone will now be in DFU mode

As limera1n performs its exploit you will see the image of a lime raindrop on your iPhone.

Limera1n will let you know when it is complete.

Step 5
After you power back on your iPhone you will see a new icon on the SpringBoard entitled limera1n. Press it to continue.

Step 6
Once Limera1n opens select Cydia then press the Install button at the top right of the screen.

Step 7
Once the Cydia installation has completed you must reboot your iPhone.

When your iPhone has restarted you can run Cydia. Let it do all the necessary updates

NOTE*: To remove the limera1n icon from your desktop you can install CyDelete from Cydia then use it to delete the application as you delete regular AppStore apps.

UPdate: To have access to the root file system of your iPhone (via file managers like iFunBox) install application called afc2add in Cydia.

If you need unlock – install ultrasn0w via Cydia. Works for up to iOS 4.0.2.
