If you’re a big Instagram fan but you have a BlackBerry 10 device, which Instagram does not support, you’re in luck. An older version of Instagram has been ported to BlackBerry 10 and is now available for download. Keep in mind that this is not a BlackBerry 10 app, but rather an Android app that can be sideloaded onto your BlackBerry 10 device. The experience isn’t great and there are some definite bugs if you run Instagram on BB10, but this is a good solution if you want Instagram and don’t want to switch to iOS or Android.
You can download the Android version of Instagram to your computer using the link below and then you can load it onto your BlackBerry 10 device. Don’t say we didn’t warn you, though. There may be issues that arise when sideloading an unauthorized application onto your device.
