[How To] Jailbreak iOS 5.0.1 / 5.0 On iPhone 4, 3GS, iPad And iPod Touch 4G With Ac1dSn0w Beta 1

Today is the day of jailbreaking tools. With the news of release of C-Dev reporter by Chronic Dev Team which will send crash reports to Chronic Dev Team servers (instead of Apple’s) so they can find exploits, now that news has been followed up by the news of yet another jailbreaking tool. It’s called Ac1dSn0w and it jailbreaks iOS 5/iOS 5.0.1 tethered on OS X Snow Leopard and Lion.

Although, Ac1dSn0w isn’t really different from established tools like Redsn0w and Sn0wbreeze but it is a promising alternative with its features like remote jailbreaking, custom firmware creation and iRecovery Remote. Also, it is currently available for OS X only.

From PwnDevTeam:

I’m pleased to announce that we’ve just released Beta 1 of Ac1dSn0w for Mac OS X Lion (should alsowork on Snow Leopard). Ac1dSn0w allows you to jailbreak your iDevice tethered.  It also provides features like Tethered Boot, Pwned DFU, and Exit Recovery to get your device out of Recovery Loop.It currently supports iPhone 3GS, iPhone 4, iPod touch 4G and original iPad on iOS 5 and iOS 5.0.1 for tethered jailbreak. Once you go through the steps, your device will be jailbroken tethered, just like redsn0w or sn0wbreeze. iPad 2 and iPhone 4S are NOT supported.

Step 1: Download Ac1dSn0w [Google Docs Link] and launch it.

Step 2: Connect your supported  iOS device via USB with your Mac.

Step 3: Turn it off.

Step 4: Click on Show Assistant, follow on-screen instructions to enter DFU Mode.

Step 5: Once your device is in DFU mode, simply click on  Jailbreak from Ac1dSn0w and let it do its thing.

Step 6: Your iOS device will reboot after jailbreaking.

Step 7: Put it into DFU mode again. Click on Tethered Boot from Ac1dSn0w to jailbreak tethered on iOS 5 or iOS 5.0.1.

If you followed the steps correctly, your iOS device will now boot in tethered jailbroken state with Cydia installed. If you wish to restart your device, you will have to go through Step 7 each time you wish to boot into tethered jailbroken state.

For semi-tethered jailbreak, simply install “SemiTether” package from Cydia’s BigBoss to get semi-tethered jailbreak working on your iPhone, iPad, or iPod touch.
