How To: Jailbreak iPhone/iTouch using Cydia on JailBreakMe

As you know, the iPhone Dev team has released a browser-based jailbreak tool known as jailbreakme that is capable to jailbreak all models of iPhone including iPhone 4, 3GS (both old and new bootrom) and 3G running on the latest version of iOS (i.e. 4.0 or 4.0.1).

If you have used Spirit before, you should enjoy the one-click jailbreak process. But I can say “Jailbreakme” is even simpler and more user-friendly than Spirit. It is so simple that I wonder if I still need to write a guide for it.

Anyway, to let those who do not familiar with the jailbreak process, here is the step-by-step guide to show you the process.

Before jailbreaking…

Before you jump to the jailbreak procedures, please read through the points carefully:

As usual, before kicking off the jailbreak, remember to backup all your iPhone data via iTunes. You can simply connect the iPhone to your computer and sync all the data. This step is crucial. In any case you are stuck in the jailbreak process, you can always restore your iPhone back to the original state.
Though JailbreakMe should work with iPhone OS v3.x, this guide is intended for those running iOS 4. So, I suppose you have upgraded to iOS 4.0 / 4.0.1. If not, please upgrade it via iTunes.
JailbreakMe should also work with iPhone that has been jailbroken with blackra1n or Spirit. But before using JailbreakMe, please restore the iPhone to iOS 4.0 / 4.01 via iTunes.
JailbreakMe will not hacktivate your iPhone. Your iPhone should be activated before using the browser-based jailbreak tool. You can either purchase an official SIM card or simply borrow it from your friend to activate the iPhone. Alternatively, you can also try out the phonebook SIM card to activate it.

Jailbreaking iPhone with JailbreakMe

1. As JailbreakMe is a browser-based jailbreak tool, no software download is required. All you need to do is to launch the mobile Safari on your iPhone and point it to

Tip: If the above link doesn’t work, you can also try out

2. Next, you can simply slide the “slide to jailbreak” slider to kick off the jailbreak process.

3. The whole jailbreak process will take several minutes to complete. Once done, the tool prompts you that cydia has been added to your iPhone.

That’s it. Is it the simplest jailbreak tool you have ever used?

After jailbreaking… and you need to unlock

For iPhone 3GS and 3G user, if you need to unlock the iPhone, you can launch cydia and install ultrasn0w.

For iPhone 4 user, the iPhone Dev team will release an updated version of ultrasn0w to unlock iPhone 4 in these two days.

Not Working? Try again!

For some reasons, you may be stuck after you kick off the jailbreak process. In that case, you can simply reboot your iPhone and go through the whole process again. Usually, the jailbreak should work normally for the next trial.

If you have successfully jailbroken your iPhone, I hope you can leave us comment and share the iPhone model & OS version. You are also welcome to leave us questions in case you find any difficulties during the jailbreak process.

Enjoy jailbreaking!
