WhatsApp will also end support for Nokia S40, Nokia Symbian S60, Android 2.1, Android 2.2 and Windows Phone 7.1 by the end of the year. From the WhatApp blog:

While these mobile devices have been an important part of our story, they don’t offer the kind of capabilities we need to expand our app’s features in the future. This was a tough decision for us to make, but the right one in order to give people better ways to keep in touch with friends, family, and loved ones using WhatsApp. If you use one of these affected mobile devices, we recommend upgrading to a newer Android, iPhone, or Windows Phone before the end of 2016 to continue using WhatsApp.

The company said it was making this decision so it could “focus our efforts on the mobile platforms the vast majority of people use.” Here’s what Blackberry users want to say about this:

Who can blame them, even BlackBerry shows little to no support for their end users. Whatsapp for BB10 was definitely one of the better developers constantly improving and adding features. BlackBerry screwed the pooch again, they don’t deserve any loyalty. Bye bye BlackBerry, you deserve it!
