    How to Back Up iPhone Baseband

    Baseband is a general term used to describe the component of iPhone that handles calls and access to the Internet. It is a small chip that mainly handles calls and access to the Internet while other components handle other features of the iPhone. You can think of baseband as a dialup modem that is used in home PC’s to connect to the Internet and sometimes even used to send faxes.

    To make sure that your iPhone is always up-to-date, Apple frequently releases new firmware versions that might include OS or baseband updates. However, for jailbroken iPhones updating the baseband is not a good option.

    Preserving iPhone baseband allows you to restore your iPhone later, in case; you accidentally jailbreak your iPhone to an incompatible firmware. In simple words, if you back up iPhone baseband now, you have the chance to restore your iPhone later.

    For a guide on how to back up iPhone baseband, continue reading the steps below. If you are jailbreaking your iPhone using TinyUmbrella, make sure you follow Step 3. Without step 3 in action, you may accidentally update your iPhone baseband.
