As of April 2012, free social media icon sets Somacro and Somicro get an extra icon for the mobile social network Instagram. The icon for Stumbleupon has also been updated to its new logo and color. Now let’s hope instagramers will be satisfied! ;)
If you are interested in downloading the free icon sets, simply click on the images below to reach the page of each series (you will then find the download button is at the bottom of the page).
