BBM app is available on android market and can be downloaded easily. I downloaded it when few months ago it came. This is another messaging app. i personally doesn't like it. i didn;t find any good reason that i should not delete this app. the app has same all functions that my already installed messaging apps have. Delivery of messages is not so fast . it requires more data usage. the quality of images get poor when we send them trhough bbm. it had a class when it was only used for bbm and now when it's avilable for all then that also is not the point. the audio notes , chats all features are more user friendly in other messaging apps. BBm also requires more ram and processor which a mobile with 512 MB ram can't afford. as this will only slow down the speed and there will be hanging problem. moreover bbm has many bugs they are trying to fix them with updates but why to use BBM when we don't have a different feature. so the app is not bad but still i will recommend you to try other messaging apps as there are many more good apps in the market which are worth trying and spending time.
