When I first moved to Windows Phone, the major problem that I faced was that it was hard to find good applications. I thought, why shouldn’t I make a list of applications that are worth using. Given that the list can be huge, I have divided the list into three posts, the first one is everyone’s favourite. The best apps for social networking addicts. Your feedback is very important for us so please send in your suggestions and feedback.

Facebook 
Price : Free Section: Social Size: 1 MB Our suggestion is to use the ‘People Hub’ for Facebook updates and use ‘me’ application to post to Facebook but if you want a dedicated app, this one is more than enough. There may be few unofficial apps but this one just works. 4th & Mayor (FourSquare client) 
Price : Free Section: Social Size: 1 MB To be frank, the official FourSquare application is among the worst applications that are designed for Windows Phone. Most of your checkins will be off-the-grid and FourSquare says that mayorships will not be awarded to those using FourSquare for Windows Phone. 4th & Mayor is the best FourSquare client available for Windows Phone users and you get all the features that you usually get with FourSquare application and also, the notifications are very good, live tile works well. Nimbuzz 
Price : Free Section: Social Size: 1 MB This is the best chat application available on Windows Phone.

Though there is no official application for Reddit fans, this application is the best one for Reddit lovers. G+ Launcher 
Price : Free Section: news + weather Size: <1 MB Thanks to Google not releasing proper APIs and unavailability of official application for Windows Phone, this is the best you can get for Google Plus.
