So what's in it for me?

A great question. Here is the answer.
The mobile network that you subscribe to can actually deliver pretty interesting ways to socialize and share content .
They can weave uploading and sharing with real time SMS notifications and location information. They can also tie all this seamlessly into your favourite phone and make sure it works.
Your operator can also afford to promise to keep your data confidential and deliver you services on your terms, not theirs. 
And now, they can do all this with global connectivity so all your friends, all over the world can vibrate your pocket in real time with comments on your latest uploaded images, music or videos.
