How to jailbreak iPhone 4S and iPad 2 on Windows now via redsn0w CLI 0.4.3


Not possible as of right now. The only baseband for iPhone 4 that is software unlockable is 01.59.00 - others are possible with Gevey SIM but I don't believe the .08 version is covered. We'll have to wait for a software unlock to be possible or for Gevey to be updated.

Why is it too hard to use an iphone? with android (with more than 1gb cpu) i can do much more things easier. And i can personalize my phone instead of use what apple wants me to use ;)

Apple decides what is best for you and they thought changing your wallpaper and rearranging your icons is enough customization for everyone.

+1 to this, I don't need to spend all my time modding my phone and customizing my home screens, I need everything to be where it needs to be and work when it is supposed to work. My iPhone 4S handles these things perfectly.

i like 99% of what apple does better then android. And i don't care about customizing my phone. it just needs to work.

Keeps giving me "The system cannot find the path specified" when in command prompt.. Please help

head over to the forums via the how to link and post help requests there. odds of your question getting answered are far greater than in the article comments.

Move cinject to folder C:/ in your computer then copay and paste the code above, had the same problem before

I have a Mac but it doesn't load up. I think due to 10.5. Eh Oh well. Wait for windows or VMware it on my work laptop.

The best way to do this is to do a reset first erasing all content and data. Follow the steps to jailbreak and once jailbroken do another reset but this time only select reset all setttings. Once the phone comes back restore from back up using icloud. Now you will have all your data back but still be jailbroken.

Guys this isn't that hard to do. I didn't reset anything and Im running fine. It's basic command line. Honestly you can copy and paste if you feel more comfortable. I'm just happy I was able my iPad 2 jail broken.
