Social icons

Hey Dribbblers! How is it going?
I think that's time to update my social icon set that really help me in my work:) It is absolutely free and 100% shape! What's new:
— update logos for some services like Google +, Foursquare, Deviantart etc.
— add Platform icons: iOS, Android, WP
— add Messenger icons like: Slack, Viber, Whatsapp etc
Enjoy!
