Get this. Before now, Snapchat wasn't good for actually chatting. I know, for an app with chat in the name, you would understandably expect it to foster some form of conversations (the snappy kind, at least). But until now, users have only been able to take photos or short video clips, doodle on them, add captions, set how long the recipient could view them, and share. The app was less about communicating and more about, well, other stuff.
AT&T has long had a chip on its shoulder when it comes to video chat apps running on its network. It took a few years to enable Apple's solution, but Android users were stymied just last week when the new Hangouts app refused to connect to video calls over AT&T's 3G and 4G. The rationale the carrier is using to justify its decision is incredibly convoluted, to say the least. However, things are going to change in the second half of 2013.
The most noticeable addition in the latest version is that users can now hold 4-way video calls right from their phones, taking advantage of fast Wi-fi and LTE connections to display multiple video streams all at once. This gives the service a big advantage against competitors such as Skype, which only allows free users to chat with one person at a time.
