BlackBerry Messenger has gotten more competition this morning as Samsung has officially released their ChatOn Messaging app on BlackBerry. BlackBerry becomes the third supported operating system supported by ChatOn (Android and iOS being the first two) and is currently only available for download OTA (not in App World).
The app itself is pretty cool. It's definitely not a BBM killer but it is very stable and does the job as intended. How it will function in terms of battery life, memory management; etc is still yet to be seen but it is very apparent that Samsung does see BlackBerry users as relevant when it comes to messaging. If you do try ChatOn let us know how you like it!
