I am sure you would agree with me that the Z10 is a one hell of a well designed device from Blackberry coupled with full gesture-base user-interface.
To cut things short, here are steps on how you sideload whatsapp into your blackberry z10.
First of all, you need to download some programs to your computer before sideloading the app.
- Download and install the Java Runtime Environment suited for your PC. - Link
- Download and install the DDPB installer - Link
- Download Whatsapp bar file - Link
Next, you're going to open up the DDPB program from your PC you've downloaded and installed previously. Once up and running, connect your BlackBerry to your computer using the USB cable. Key in the IP address where it says "IP Development Mode" and click Scan. Key in the device password and click connect. (It will be the same password which you previously created when enabling Development Mode)
Once your device is connected with DDPB, simply click on the "Add" button then browse to where you stored your downloaded .BAR files and add them to the list.
Wahhh lahhhhh, your app will be installed.
Last but not least, please proceed to turn off the Development Mode.
Enjoy your Z10 and Whatsapp!
