How do I delete my Facebook friends from the mobile interface?. Before the timeline feature there was an "unfriend" button in their profile. However, now I can't find where is it located in timeline version of Facebook.
It is very simple. Just see this screenshot:
You have to first click on the "Friends" button, then you see a pop-up drop down list, at the end of which you have the option of "Unfriend".
PS: Kindly note that, based on your mobile model, the mobile browser/facebook app you are using, the kind of script that runs when clicking on "Friends" here may not be supported, in which case you will not be able to "Unfriend" anyone.
