Smartphones iPhone is a well-known multimedia device from Apple. To take advantage of various additional features of your device and add new applications, you need to determine the iPhone firmware version.
Instructions
Step 1
Look closely at the box of your iPhone. If you have a fairly early version, then a sticker may be glued on it, which indicates the firmware version of the device. Otherwise, you must first activate your phone via iTunes before determining the version.
Step 2
Find the Settings menu on the home screen of your iPhone. Go to the General tab and then select the About section. All information about the device will be presented here. Scroll through the text until you see the iPhone serial number and firmware version. For example, there may be an inscription 4.2.1 (8C148). Rewrite this information on a separate sheet so that you can reflash the device in the future.
Step 3
Turn on your iPhone and navigate to the keyboard via the Slide for emergency function. Dial * 3001 # 12345 # * and press the call button. A service data menu will appear - scroll down and find the Versions section. Rewrite the data indicated next to Fireware version. They can be used to determine the firmware version. So if 04.26.08_G is written, then this corresponds to version 3.0, and for the inscription 04.05.04_G - version iPhone 2.0. Compliance information can be found on many iPhone sites on the Internet.
Step 4
Find the serial number of the device on the box next to Serial No. Also, this information can be found on the phone under the battery. Find the 4th or 5th number of the serial number, which indicates the week the device was manufactured. Depending on this, the firmware version can be determined.
Step 5
To do this, find a special table on the Internet. For example, if the number is less than 38, version 1.0.2 corresponds to it. This method cannot always be used to determine the version, since it is inaccurate and requires confirmation by other methods.
