How to determine your firmware version

This website's tutorials are written for specific firmware versions. Some tutorials will work on other firmwares, but it is up to you to determine that. Each firmware has its own section on this site. Older firmware tutorials can be found in the "Deprecated tutorials" section. This particular page does not have a standard navigation bar. There is only one button here, and it's to go back to the home page.

To determine which firmware you have on your iPhone, press the Home button, then the Settings button, then press General, then press About. Look for the entry for "Version". It will have a number next to it and another number in parantheses. We're only concerned about the first three digit number. In my example I have 1.1.2 firmware.

If you have a new iPhone that hasn't been activated or modified, then this is what you must do to determine what firmware you have. You will see one of two screens on your new iPhone when you turn it on. The image on the left is associated with firmware 1.0, 1.0.1, 1.0.2 and 1.1.1. The image on the right is associated with firmware 1.1.2 only.



To further determine if you have 1.0, 1.0.1, 1.0.2 or 1.1.1 firmware there is one more thing that can easily be performed. At the main screen on the iPhone, slide the slider to access the emergency call panel. Enter *3001#12345#* and then press the Call button.





You will now see this screen. Press the Versions menu. You'll see the infamous typo menu entry called Firware version. This is actually supposed to say firmware version. This particular firmware number refers to the modem version.

• 1.0 firmware came with 03.11.02_G modem firmware.
• 1.0.1 firmware came with 03.12.08_G modem firmware.
• 1.0.2 firmware came with 03.14.08_G modem firmware.
• 1.1.1 firmware came with 04.01.13_G modem firmware.
• 1.1.2 firmware came with 04.02.13_G modem firmware.

There is another method to determine exactly which version you have, but it is more lenghty and an unneccessary procedure.
