With the advent of iOS 4.3, one could easily find that Apple is more focusing on bringing social features like Find My Friends for MobileMe. This will provide real time location data of their friends.
MobileMe helps you to keep your mail, contacts and calendar information in the cloud and sync everything across your iPhone, iPad, Mac,PC and web.
In speculation, Apple will add two additional social features like Media Streaming and Photo Streaming into MobileMe. With Photo Stream, users will be allowed to invite other users to view your pictures as you take them. We guess Find My Friends will be another aspect of Apple’s social network as part of a free MobileMe. You can also choose to view your friends Photo Streams all on that same map.
