Redsn0w update to 0.9.10b5c Version b5b fixes an issue with using custom ramdisks on iPhone3G and iPod2G, and version b5c prevents redsn0w from crashing due to the ever-growing ramdisk size.
Corona update to v1.0-
It has been nearly eight weeks since the first declaration by pod2g that he had found a bug that he believed could provide an untethered jailbreak for iOS 5. We find ourselves exactly fifty days down the line, and what I imagine has been a lot of sleepless nights for the developers involved, but we now officially have the release of an untethered jailbreak for all A4 devices running iOS 5.0.1.

iOS 5.0.1 Untethered Jailbreak

On December 22nd, pod2g announced via his official blog that would be passing all of his work and details across to the researchers at the Chronic Development Team partly to allow him to concentrate on progressing the development of an A5 jailbreak, and partly because he believed that the Chronic Dev Team could integrate and package all of his work into a distributable jailbreak.

It seems that his instincts were correct as only five days after that decision was made, we are seeing a release of a jailbreak for A4 devices on iOS 5.0.1 which has been implemented by both the Chronic Dev  and iPhone Dev teams.

The iOS 5.0.1 untethered jailbreak contains the exact same set of files that pod2g provided to the Chronic Dev Team, and can be distributed as either a download via Cydia by searching for a package named ‘Corona’, for users who are already jailbroken tethered, or through a Redsn0w bundle for users who have running stock iOS and have been waiting for this untether.

At the time of writing, it is worth noting that this jailbreak currently only supports iOS 5.0.1 with Chronic Dev Team member p0sixninja tweeting out that 5.0 will follow soon after a number of small bugs have been eradicated and more testing has been carried out. Pod2g has also released some advice to A4 and A5 users advising not to update their devices to iOS 5.0.2 or 5.1 when released as this would cut their chance of a future jailbreak.

Note: The jailbreak released is supported on all A4 based (and below) devices like iPhone 4, 3GS, iPod touch 3G/4G and iPad 1. Newer A5-based devices like iPad 2 and iPhone 4S are currently not supported.


For Users On iOS 5.0.1 Tethered Jailbreak : [Corona 5.0.1 Untether Cydia Package]

If you are currently operating an A4 device which has a tethered jailbreak using Redsn0w, Ac1dSn0w or Sn0wbreeze then you can simply launch Cydia from your Springboard and download a package named ‘Corona’ which will provide you with an untethered jailbreak.


For Users On Stock iOS 5.0.1:

If your device is running stock iOS 5.0.1 then you can use download the latest Redsn0w 0.9.10b1 to for either Windows or Mac to give yourself an untethered jailbreak, instructions for which can be found below.


Step 1: Download the latest version of Redsn0w from the links given above.

Step 2: Start Redsn0w, select “Jailbreak” then check “Install Cydia“. Follow the onscreen steps to place your device into DFU mode.

Step 3: Wait for Redsn0w to apply the full untethered jailbreak!

Once done, your iPhone, iPad or iPod touch will be rebooted into fully untethered jailbreak mode!

  7. ErKo says:

    While I´m jailbreaking with redsnow, it stays at “uploading first step” when the blue baar is full; then redsnow dissapears and it stops jailbreaking!!! What is happening?

  8. Inquiry says:

    I have an iphone 4 running “Tethered” ios 5.0.1 jailbroken via sn0wbreeze’s custom firmware to preserve baseband because I am relying on Gevey unlock. If I download corona via cydia, will it still preserve my baseband?

  9. Chris says:

    Trying to jailbreak an IPod Touch 4G running IOS 5.0.1 using redsnow but I keep getting a message saying that there is no device detected and that I may have failed to follow the instructions on entering DFU. I did the instructions from redsn0w and even tried the 10 sec power+home then 10 secs more on just home but I still get the same error. What am I doing wrong? Please help… Thanks!
