How To: Jailbreak iOS 5.0.1 On iPhone 4, iPhone 3GS With RedSn0w 0.9.9b9 [Mac OS X]

Yesterday we told you that the Dev-Team released RedSn0w version 0.9.9 beta 9 to Jailbreak the iOS 5.0.1 firmware, without having to point RedSn0w at the iOS 5.0 firmware. Additionally, this new version of RedSn0w will fix the iBooks crashing issue on Jailbroken iDevices, along with multiple other bug fixes while Jailbreaking on the iOS 5.0/iOS 5.0.1 firmware generation.

As the Jailbreaking process has changed while using RedSn0w 0.9.9b9, we will be covering how to Jailbreak tethered your iPhone 4 and iPhone 3GS running the iOS 5.0.1 firmware using RedSn0w 0.9.9b9 on the Mac OS X operating system.

Step 4) – After clicking the Jailbreak button ensure that the “Install Cydia” option is checked, click the Next button and you will come to a screen where you will need to put your iPhone into DFU mode. Read through and follow the instructions presented to you which is to plug in and power off your iPhone and click the next button.

Step 5) – When you click the next button you will need to follow the instructions presented to you to actually put your iPhone into DFU mode.

• Hold down Power (corner) button for 5 seconds.

Step 6) – After you successfully enter DFU mode RedSn0w 0.9.9b9 will begin jailbreaking the iPhone. DO NOT interrupt or use the computer during this time. When the iPhone is finished being jailbroken it will reboot into a jailbroken state.

Optional: Booting Tethered – When you Jailbreak the iPhone running the iOS 5.0.1 firmware you will have a tethered Jailbreak. Meaning in order for your iPhone to turn back on you will simply need to boot it using RedSn0w (this applies every time your iPhone loses power). To do this launch RedSn0w again and click the Extras Button > then click the Just boot button and you will need to put the iPhone into DFU mode again.

Note: Yes, you need to do this every time the iPhone loses power.

Optional: SemiTethered Jailbreak – Though you have now Jailbroken your iPhone tethered on the iOS 5.0.1 firmware, you can actually SemiTether your iPhone. SemiTethering your iPhone basically means that you will be able to still use it if it ever loses power (with limited functionality). In order to SemiTether your iPhone you will need to add the following repository through Cydia:
