WhatsApp was the first to reach the battle for mobile messaging, and hence proceeds much of his success. As described in his blog, when WhatsApp began their wanderings in 2009 the mobile ecosystem was very different: the 70% of mobile selling system they had Nokia or BlackBerry.

It is not surprising therefore that WhatsApp is available for a range of platforms “minority” that a new application would normally overlook. This is the case of the version of WhatsApp for Symbian, Nokia Series 40, Blackberry or older versions of Android like Android 2.1.

Times have changed in seven years, and now mobile with Android, iOS and Windows Phone system account for a whopping 99.5% market share. Not seem to make much sense to continue efforts to maintain version for systems with “as few users”, and therefore the official support Android 2.1, Blackberry, Nokia and WP7.1 will end before the end of the year.

Updated or die

In WhatsApp they have taken stock and decided loaded support for operating systems that have the least amount of users. This is the case of the full branch of WhatsApp for BlackBerry (including BlackBerry 10) and all phones Nokia (Symbian Series 40).

Other operating systems will continue running but will break compatibility with older versions. This is the case of Windows Phone, which will lose the support for Windows Phone 7.1, and Android, where compatibility with Android 2.1 and 2.2 (Eclair and Froyo) will not be a problem when upgrading.

This does not mean that WhatsApp stop working the overnight on your mobile old, but basically WhatsApp will give the same whether it works. These systems will be left to their fate, where probably continue to operate in both WhatsApp not make fundamental changes to its communication protocol.

The recommendation of WhatsApp for you lidies with this genocide Whatsappil is obvious: it is time for you to do with a phone with a newer version of Android, iOS or Windows Phone, at least if you want to continue using WhatsApp.
