Papaya
Papaya turns your phonebook into a fun and useful social network! It allows you to communicate with your friends cheaply and easily, no matter where you are. Using Papaya, you can play games with your friends, chat with them over IM, share pictures and other files, make cheap international calls, and more.
Papaya has three parts and each part works individually. These three parts are: an application to be installed on your cell phone, a mobile website (WAP site) that allows you to use most of the features on your phone without installing anything, and a website where you can sign in.
