GigaOM reports that Symbian is about to announce a significant upgrade to its operating system on Monday at CTIA. According to ABI Research, Symbian held a commanding 73% market share of the loosely defined Smart-phone market in 2006, resulting in about 50 Million shipments. 

Improvements include battery and memory management, camera and multimedia enhancements and the introduction of transparent and automatic roaming between WiFi and 3G. MobHappy brings the full details.

The upgrade is very significant for a number of reasons. Symbian is reaching out of the Smartphone niche. The multimedia boost, for example, is clearly a consumer focus. Push email and Voip are communication apps and not “business apps” anymore. Symbian is slowly but surely building an attractive and real consumer position, realizing that the higher end market would pay a little more for high quality feature phone.

The introduction of transparent WiFi - 3G roaming is even more significant. While full handset OEM support is needed, this has the potential of making operator independent mobile internet actually usable. Very few users actually bother with switching networks on an ongoing basis. Making the switch automatic would not only reduce costs for the end user, it would also break a wide open hole in the walled garden. And this does not only apply to browsing but to the very core - phone calls. Now, I don’t see Mobile VOIP going mainstream very soon, but I definitely see a gradual uptake, mostly by the cream of the crop from an operator point of view - the travelling professionals.  

How will Operators deal with this? Good question. So far everybody’s happy with the containment of Symbian devices as “Smartphones”. It makes it easy for everyone to avoid a clash. Some operators force vendors to take off the WiFi feature for now (Cingular and Nokia E62 for example). Some put a more constructive focus on upgrading their 3G networks. In any case, it’s all a prelude to the unavoidable reshuffle of the mobile universe.
