Jailbreak iOS 4.2.1 with Greenpois0n RC5_2 on Mac OS X Leopard

Many iPhone users are finding hard to untether jailbreak on iOS 4.2.1 using Greenpois0n 1.0 RC5, to run on Mac OS X 10.5.x. The Greenpois0n tool open and then close immediately. It is because GreenPois0n RC tries to call version 6.0.0 of libcurl.4.dylib, but gets 5.0.0 in return. Due to this the application closes out immediately. Follow the simple steps listed below to make the jailbreak run on Mac OS X Leopard.

How to make GreenPois0n RC5_2 work on Mac OS X Leopard 10.5.x

Step 1. Download this filelibcurl.4.dylib v6.0.0
Step 2. Extract the file in your downloads folder.
Step 3. Launch
Step 4. Type: sudo rm /usr/lib/libcurl.4.dylib
Step 5. Enter password and hit enter.

LG Optimus Pad confirmed for MWC 2011 with Honeycomb

LG spilled the beans on the T-Mobile G-Slate earlier this month, and now its European counterpart is getting ready to make its own debut. A Korean press release has confirmed that LG intends to properly launch the LG Optimus Pad at MWC 2011 in a little over a week’s time.

It’s been a long journey, too, from the first talk of the Optimus Pad back in mid-2010. The slate is expected to be a European 3G version of the G-Tablet, with NVIDIA’s Tegra 2 processor and an 8.9-inch capacitive touchscreen display along with a 6,400 mAh battery; as you can see from LG’s press shot, it runs Android 3.0 Honeycomb.

Sony’s Kaz Hirai talks NGP with Official PlayStation Blog

as never that impressed by the original PSP, the games on the system weren’t that great and the portable device itself was just not as fun as the Nintendo DS to me. When Sony unveiled the NGP last month the new portable looks great and I am excited about it. The unveiling of the NGP early in the year for a launch near the holiday season of 2011 left a lot of us wondering why the console was announced so early.


Sony’s Kaz Hirai has sat down for an interview with the Official PlayStation Blog about the NGP to answer a few questions. The reason the console was announced so far ahead of the launch according to Hirai was so that Sony could talk openly about the portable with game developers all around the world. Sony wants a large and robust list of launch titles for the portable and should have it.

We all know that the details would have been leaked in short order as Sony lined up developers so this was a preemptive move it seems. Hirai also noted that having a stable platform that would stay for years to come was important in the developing stage of the new portable. He also said that Sony hopes to match the install base of the PSP and then move beyond that with the NGP. Check out the video to hear what he had to say.

Jailbreak iPhone 4 4.2.1 iOS with Greenpois0n RC5 & Unlock with Ultrasn0w [Old Baseband]

If you have the unlocked iPhone 4 on baseband 01.59.00 and you want to update to iOS 4.2.1, your baseband will likely be updated to 03.10.01, losing carrier unlock. Updating to iOS 4.2.1 using TinyUmbrella will protect your baseband update and later allowing you to carrier unlock your iPhone 4 again. Follow the tutorial on how to upgrade your iPhone 4 to 4.2.1 preserving its baseband using TinyUmbrella.


Before proceeding you must have Saurik’s server in your host file. At the end of file add the string useful to redirect requests for certificates for authenticity that iTunes will make to the Saurik server. You may follow the steps below to do so.

Windows users

  • Open Notepad with administrator privileges and then right click on the icon of notepad and click on “Open as administrator”
  • Now that Notepad is open Go to folder C:/WINDOWS/system32/drivers/etc and open the file
  • Add the following line at the end of the document and save it:

Mac users

  • Navigate to Go -> Go to Folder and enter the path /etc
  • Open the file hosts with TextEdit, add the following string save the file to your desktop.
  • Now return to the previous folder by following the same method and copy the text within this file by replacing the original file (If prompted for a password enter it and click OK)

Untether Jailbreak iPhone 4 iOS 4.2.1 with Greenpois0n & Unlock using Ultrasn0w

Step 1: Update iTunes to iTunes 10.1.2

Step 2: Download TinyUmbrella from here.

Step 3: Connect your iPhone to your Mac

Step 4: Right Click the TinyUmbrella and select “Run as administrator” to open it. If you get a Windows Security Alert, make sure both boxes are checked, and hit Allow Access

Step 5: Verify that your device is currently connected, so that TinyUmbrella can detect the type of device and its firmware.

Step 6: Make sure Cydia or TinyUmbrella has an SHSH of the latest firmware. You can do this by simply clicking “Save my SHSH”. (at this point TinyUmbrella attempts to check for your SHSH blobs on Saurik’s server as well as save your current ones locally)

Step 7: Minimize TinyUmbrella (we will not be using TinyUmbrella’s TSS Server for this as it won’t allow localhost resolution)

Step 8: Open iTunes

Step 9: Backup you iPhone (anytime you do an update or jailbreak you must backup your phone)

Step 10: iTunes will offer you the update to 4.2.1 click Download and Update

Step 11: Once your installation has started it will take a couple of minutes to actually complete

Step 12: After your phone reboots for the final time iTunes will error out with a 1013 error. This is what we were looking for. Notably, the baseband has not updated.

Step 13: Close all of iTunes error pages and iTunes itself

Step 14: Go back to TinyUmbrella

Step 15: Click Exit Recovery and you phone should be rebooting and will come up to the home screen

Step 16: Go to Settings>General>About verify that you are still on the same baseband as before

Step 17: Jailbreak your iPhone 4 iOS 4.2.1 on baseband 01.59.00 using Greenpois0n RC5.

Step 18: Carrier unlock your iPhone 4 iOS 4.2.1 using ultrasn0w


Redsn0w 0.9.6rc7 Released ! Brings One-click Tethered iOS 4.2.1 Boot !

The iPhone Dev Team has just released a new version of Redsn0w with one-click tethered iOS 4.2.1 jailbeak boot support. Redsn0w 0.9.6rc7 includes “one-click tethered boot” support for those of you running the tethered 4.2.1 jailbreak.

With Redsn0w 0.9.6rc7, you can use command-line arguments so you can now bypass the screens you’d normally see as you use redsn0w to “Just boot tethered for now” when your device is rebooted.

Here’s the update from the official blog:

We’ve updated redsn0w to include “one-click” support for those of you
running the tethered 4.2.1 jailbreak. Using command-line arguments,
you can now bypass the screens you’d normally see as you use redsn0w
to “Just boot tethered for now”.

The available command line arguments are:

-j to ask redsn0w to “Just boot now”
-i to specify your reference IPSW
-o for old-bootrom iPod touch 2G and iPhone 3GS
to specify your own boot logo png

For example, to get redsn0w for Mac to do a tethered boot of an iPod touch 4G jailbroken at 4.2.1:

open ~/Desktop/ –args -j -i ~/Desktop/iPod4,1_4.2.1_8C148_Restore.ipsw

This assumes both redsn0w and the IPSW are on your OS X desktop, so
modify as necessary! Included in the zip is an example script file
that you can double click on to launch redsn0w like this (the Windows
example assumes everything is in C:\). (Mac users: please remember to
change the permissions of your custom *.command files to allow

This should help ease the pain of the tethered jailbreak until @comex
comes up with a 4.2.1 untether (or for those of you with legit access
to the 4.2b3 IPSW, until the “Jailbreak Monte” untether is out of

– Make sure you’re using a USB 2.0 port

Please note that the iPhone Dev Team is working on untethering iOS 4.2.1 jailbreak so you don’t need to connect your iOS device everytime it reboots. They are have released Redsn0w 0.9.7 beta for Mac OS X, you can try the latest release of this beta but you need iOS 4.2 beta 3 hashes and IPSW file.

Download Redsn0w 0.9.6rc7 for Windows
Download Redsn0w 0.9.6rc7 for Mac OS X
Download iOS 4.2.1 for iPhone, iPad and iPod touch
Download iTunes 10.1 for Windows and Mac OS X
