Apple iOS 5.0.1 jailbreak for iPhone 4 and 3GS is now available. I have tested it on my iPhone 4 and even semi tethering application is working. However, it does not works with iPhone 4s. Ready? Follow these jailbreak instructions:
First, make sure you are running the latest version of iTunes. Grab it from Apple’s website. Update your phone to the 5.0.1. Download the iPhone 5.0.1 IPSW and proceed to the next step.
Download Redsnow for windows / mac. Start it > Select ‘Extras’ > ‘select IPSW’ and browse for the file you downloaded earlier.
Click on ‘Jailbreak’ > ‘Install Cydia’. You will now be told to put it into DFU mode as only then Redsnow can do its job.
Now, since this is a tethered jailbreak, you will need to start Redsnow again and select ‘extras’. Now, click ‘Just boot’ to start your iPhone. To get the semi tethered boot, follow our post about iPhone semi tethered jailbreak.
