How to jailbreak Iphone 4

The process will be explained for an Iphone 4, however it can be used for the following ones models:

- iPhone 3GS

- iPod touch 3G

- iPod touch 4G

- iPad 1

In addition, we must have the following archives:

Sn0wbreeze 2.7.1 :

Firmware 4.3.3 of our device: iPhone firmwares

First of all, we will explain how to carry out the jailbreak to our mobile. The jailbreak will allow us to use any home-made application, not signed by Apple, on our terminal.

First of all we must connect the mobile phone to your computer and run Sn0wbreeze that we will use during the whole process. In the first window that appears, click on Ok and we will come to the following:

Sn0wbreeze 2.7.1

After clicking on Browseselect the Firmware 4.3.3 that we have previously downloaded. The programme will check that the file is in good condition and then click on the arrow in the bottom right-hand corner.

In the next window we select Expert Mode to be able to specify the settings we are interested in and click again on the arrow.

We then select the option General and a configuration window like the following will appear in front of us:


In this window, select the option Activate the iPhone if you do not have the official Iphone Sim.

Then we press next and return to the previous window where we must select this time Build IPSW. After a few minutes of waiting, we will see that the process is complete.

Now all we have to do is press Start and set the Iphone to DFU mode (10 seconds on+home and 15 others with only home).

After observing a message that tells us that the mobile is correctly positioned in DFU mode, the Firmware will be created and we must install it on our iPhone using iTunes.

Once we have installed the firmware, we can unlock our handset using the application Ultrasn0w 1.2.3 which is downloaded from cyndia via the repository .

As always, remember that you can go to our forum to ask any questions you may have.
