Do I have to tweak the WP8 app when developing a new app?
We are planning to develop a new application. It has VoIP function and whatsapp like app.
Since the app has Voip function, we have to go with WP8 silver. Winrt for WP does not support VOIP api.
Is it safe to assume that almost all WP8 devices have been updated to WP8.1? If WP8 still has a large user base, we will develop the application using the WP8 api (using VS2012). Otherwise, we will go to WP8.1 api (using VS2013). I've heard that WP8.1 has several performance and control improvements.
Any suggestions on this?
Thank you in advance

All Lumia phones can be upgraded to WP8.1, and a huge proportion of users have done so. Article for reference only: http://www.engadget.com/2014/04/02/nokia-lumia-windows-phone-8-1-update/ In my apps I use analytics to track users and I hardly see that some users are stuck with WP8.
Update - Market Share http://www.gsmarena.com/adduplex_wp81_market_share_surpasses_wp80-news-10062.php This article from last October WP8.1 has been released for about 5 months and has already surpassed WP8. I let you think about the actual quota ...
Should you go with WinRT? It depends on your needs. You must of course be using at least WP8.1 Silveright (not WP8). But if your application does not require special features only available in WinRT, you can go with WP8.1 Silverlight as WinRT still has a lot of performance issues.
