Facebook is one of the most popular social sites along with Twitter and MySpace. YELLIX is the app that brings Facebook to your phone.

YELLIX not only brings Facebook to your phone it takes it to the next level. It enables you to view the profile picture and status of your Facebook friends. It uses a popup that displays a profile picture, the phone number and status of your friend.

All you need is a 3G connection and a Facebook profile. Although, this may may prove to be a costly app because of all the charges that the carrier might apply to you for internet. If you have an internet data plan and you don’t use it that this is one of the many ways to do that.

Of course this only works if your friend has a phone number defined in his or hers profile. This is a great idea, but I do not use Facebook so I wish there was one for Twitter.
