5 Great Sets of Free Social Media Icons
Glossy social is an icon set which consists of 20 icons for the following services: YouTube, Twitter, Digg, StumbleUpon, Flickr, RSS, Feedburner, Skype, Last.fm, Gmail, Linkedin, Yahoo, Facebook, Delicious, mySpace, reddit, Friendfeed, WordPress, Vimeo and a generic “Favorite” icon 
In this freebie icon set, you will find 16 free social media icons for sites that designers appreciate (such as deviantART, Flickr, Twitter, and more). This free icon set is called A Life in Pixels and is inspired by Minimalist design philosophies.
The set includes 16 32px x 32px PNG files. They are monochromatic and can work with many other colors, which is perfect if you are looking for icons that are subtle and muted so that they do not dominate your design.
This is a set of 14 riveted brushed steel icons that not only include the basics but DesignBump, DesignMoo, and DesignFloat as well! You’ll find 14 different 64px x 64px icons in this set in .jpg format.
