How to Update your iPhone 4 and Prevent iPhone 4 Baseband Update

This page ONLY deals with iPhone 4 baseband protection. I'm sorry this will not work for any other device.

You can protect your iPhone 4 BB restoring to iOS 4.2.1. Follow these steps exactly:

Get the latest TinyUmbrella.
Get the latest greenpois0n rc5 update (http://greenpois0n.com)
Open TinyUmbrella
Plug in your device and save SHSH (make sure 4.2.1 SHSH were saved, if not don't bother continuing)
Start TSS Server (If you get errors read the help section or FAQs or comment below typically it fails because you have some kind of web sharing enabled... use google to fix it - your issue really not much I can do...)
Open iTunes
Select your device in iTunes
Shift(windows) / Option(Mac) restore -> Select the 4.2.1 ipsw
Restore SHOULD error with a 1013 error. Click the "ok's" and close iTunes.
With your device sitting with the usb pointing to iTunes (recovery mode), enter DFU by pressing and holding HOME + POWER until your screen goes black... then after a count of 2 (1.5-2 seconds) let go of POWER but keep holding HOME. If all goes well you will see nothing but a black screen. If your timing is even a LITTLE bit off, you will see the apple logo and your phone will boot back into recovery mode... Go back to step 10 and try again.
You're now in DFU mode. Start greenpois0n and press 'Jailbreak'
Once greenpois0n has finished its thing. Press 'Complete!'
Let your device restart. You should end up on the activation screen.
Congrats your baseband was preserved and you are now on 4.2.1

If you get a 16XX error then try entering DFU and go to step 5.

If your restore does NOT end in a 1013, it means your baseband was updated. This is likely because you did not have the TSS server running OR you updated without TinyUmbrella OR you are working with a device OTHER than iPhone 4.

iPhone Dev-Team Ports Monte Untether Back to iOS 4.1 SHSH Blobs

The iPhone Dev-Team has successfully ported their Monte untether back to the iOS 4.1 kernel.

Previously to untether your jailbreak using Monte you needed to have the iOS 4.2b3 SHSH blobs saved which was developer only. Now you will only need your iOS 4.1 SHSH blobs. The team is also working on porting Monte forward to iOS 4.3...

Ported Monte back to 4.1 kernel (SHSH blobs). Next step: porting it forward to 4.3beta!

MuscleNerd notes that the beauty of Monte is it doesn't expose any new exploits :) It makes the entire "wait until next FW" concern moot. Think of Monte as a "green" jailbreak. It recycles (for example) 4.1's exact JB exploit on 4.2.1 :) Waste no exploits.

We'll let you know when RedSn0w is updated with the new capabilities.

The Chronic Dev-Team is also packaging up an untether for iOS 4.2.1 that will not require SHSH Blobs.

Stay tuned for more information.

Zibri Discovers Evidence of Qualcomm Baseband for Next iPhone

Zibri, best known for releasing the ZiPhone jailbreak utility, has reportedly discovered evidence that the next wave of iDevices will use a Qualcomm baseband.

In the picture above you see a "chunk" of code from the latest iTunes. Maybe, for the most of you, names like "partition.mbn" or "AMSS.MBN" means little or nothing. For me and a few others that means only one thing: QUALCOMM. Those files are the building blocks of any Qualcomm baseband.

So I can tell you that the next wave of iProducts will be using a QUALCOMM baseband. Which one I don't know... maybe the iPad2, maybe the iPhone5 most probably all of them. What is clear is that they are testing them using the same iTunes you have on your hard drives.

Recent reports from Engadget and DigiTimes also predict a Qualcomm baseband for upcoming Apple devices.

Comex May Wait for Verizon iPhone Before Releasing Untether

Comex may wait for the release of the Verizon iPhone before releasing his untether, according to a tweet he sent earlier today.

i0n1c: so @comex is not waiting for the next iOS for untethering?

comex: @i0n1c I don't know, I think I'm waiting for the Verizon iPhone.

Currently, the only untether is available is the 'backup plan' from the iPhone Dev-Team. The Chronic Dev-Team has said they are also working on their own untether.

Geohot May Have Untether for Some Jailbroken Devices

Geohot may have an untether for some jailbroken devices running iOS 4.2.1, according to a tweet by MuscleNerd.

@ipodguy79 I hear geohot does have an untether actually! Though not for all devices.

Geohot is the hacker behind limera1n which is currently being used to jailbreak iOS devices. It was recently discovered that Geohot registered Rubyra1n.com; however, that name is thought to be reserved for a future exploit.

Currently, only some iOS 4.2.1 devices can be untethered via a 'backup plan' untether from the iPhone Dev-Team. Comex is also working on an untether which will hopefully be available soon.

iPhone Dev-Team to Update RedSn0w Beta Today, Windows Update Coming Soon

RedSn0w .9.7b4 will be released today to untether your iOS 4.2.1 jailbreak without the need for usbmuxd.

This untether is a 'backup plan' from the iPhone Dev-Team. It requires access to the iOS 4.2b3 firmware and your iOS 4.2b3 SHSH blobs saved.

Currently, the untether is Mac only but the next update will bring Windows support.

Today's beta4 will eliminate separate usbmuxd process (so many more Mac users can use it). After that, expand to Windows.

You can find our instructions on performing the untether here.

iPhone Dev-Team Releases 'Backup 'Plan' Untethered Jailbreak

The iPhone Dev-Team has released a beta of their 'backup plan' untethered jailbreak. Currently the beta is only for Mac users and is limited to iPhone4, iPad, and iPod touch 4G.

Important Points:
● This is a beta tester program. Things can go very wrong, so please don’t even consider testing if you have pictures or other media on your device that you haven’t backed up!
● For the same reason, please don’t participate if you rely on the ultrasn0w carrier unlock. Wait for the final version!
● Until we fix some sandbox issues with bluetooth, the bluetooth functionality is disabled.
● This very first beta1 is limited to iPhone4, iPad, and iPod touch 4G.
● You must already have the usbmuxd software installed and running on your Mac.

You can download the updated version of RedSn0w here. We will be posting our tutorial shortly!

TinyUmbrella Update Will Bypass SHSH Checks and Restore iDevice Without iTunes

Semaphore is working on an update to TinyUmbrella that will allow users to restore their iDevices without iTunes.

I've been working on a new and improved version of TinyUmbrella that will, among other things, allow you to restore your iDevice without iTunes. With the holiday season and work, this will take me a bit to get working the way I want it. I appreciate your patience and your support. You guys are awesome :) No ETAs yet but I'll post updates here and on twitter.

Semaphore explains that this means bypassing shsh checks will be possible for devices that can be exploited by limera1n (basically all devices available now) and the steaksauce exploit for the mc 2g ipod touch.

You will always be able to install a custom firmware (or stock firmware) following these directions.

1. Enter DFU
2. Run the Exploit
3. Wait for the White Screen
4. Restore the ipsw of your choice.

Some changes to the ipsw will be required. We will post more information as it becomes available.

Apple Removes Jailbreak API From iOS 4.2

Apple has removed its built in methods to help developers detect jailbroken devices from iOS 4.2, according to NetworkWorld.

This detection API let the MDM applications in effect ask the operating system if it had been compromised. Jailbreak exploits typically change a number of operating system files, and exploit one or another low-level OS features to let users directly load their own or third-party applications.

Previously, developers had created their own series of operating system checks to detect jailbreak.

"We used it when it was available, but as an adjunct," says Joe Owen, vice president of engineering at Sybase, which offers the Afaria device management software. "I’m not sure what motivated their removing that….I’ve not had anyone [at enterprise customer sites] talk to me about this API being present or being removed."

In July of this year the Library of Congress deemed that jailbreaking your iPhone in order to install applications not approved by Apple and/or to unlock is legal.
