Mobile World Congress, Europe's biggest mobile tech conference, was the site of Nokia's ruthless mining of the world's natural megapixel reserves. The Finnish company (who's lately started making phones we really like) announced the 808, a smartphone with a 41-megapixel camera, along with a sensor and flash big enough to feel at home in a point-and-shoot. That'll give the phone better digital zoom capabilities and hopefully better image quality - Nokia has a new system to take all those pixels and turn them into nicer, smaller pictures. (Oddly, the phone will use, of all things, the very dead and very awful Symbian OS.)
Our first local 4G LTE network rolled out on Telstra late last year, but in the States, LTE has been around since late 2010, with the Verizon network. The problem is that as mobile data traffic continues to grow - experts anticipate that it will increase 26-fold in the next three years - it's unlikely that any network will be able to keep up. Fortunately, something else is set to happen over the next three years: Wi-Fi could become as ubiquitous and easy to access as cellular is now.
"Siri, how do I feel right now?" Apple's automated assistant might not be so perceptive as to know, but your smartphone may soon be able to assess your mood and determine if you are suffering from symptoms of depression. Researchers at Northwestern University are creating a kind of virtual therapist called Mobilyze to help people that tend to ignore symptoms of their depression realise that they need to take measures to deal with their moods.
What do your smartphone apps say about you? Not in the "who am I and what is my place in the world?" sense, but literally - what are your apps telling other people about you? Your location? Your identity? Your username and password? The Wall Street Journal has put online a pretty amazing, sometimes outraging, definitely interesting interactive graphic analysing 101 popular iPhone and Android apps, telling you exactly what your apps are telling other people.
