Less than one month after shelling out $1 billion to acquire photo-sharing application Instagram, Facebook added two Instagram-like photo filters to its Facebook for Every Phone app.

However, a Facebook spokesperson told sister blog Inside Facebook the filters were developed by one of the social network’s engineers during a Hackathon event, and had nothing to do with Instagram.

Facebook for Every Phone allows Facebook access from feature phones, or non-smartphone mobile phones.

The social network announced in a post on the Facebook for Every Phone page:

As part of our ongoing efforts to create a better Facebook mobile experience across all devices, we are excited to announce that the Facebook for Every Phone app now has two filters, sepia and black-and-white, for your mobile photos.

Take pictures, change their look, and share with your friends straight from your app.
