Sure there is the non free way by installing the app in Cydia, but then there is the do it yourself way. So why pay for something that can do the exact same thing?

Installation

1. Install OpenSSH and set up Cyberduck on your computer. Don’t know how? Click Here.

2. Navigate to /etc/.

3. Download this replacement hosts file.

4. Drag that file to the Cyberduck window. Click on Replace when it asks you to.

5. Restart your iPhone!

Your mobile internet browsing should now be ad free!

Quick Note:  Filezilla is a free alternative for Windows Users

Big thanks to James is bored for finding an alternative solution
