Facebook chat on Blackberry can be accomplished using several different apps, and because the decision is tough every time, we will attempt to present these options so that you can make the choice yourself.
1. Blackberry Messenger
First, we have the Chat for Facebook app that you can find on the official Blackberry site. This is regarded as the most stable option because it is made by the makers of the Blackberry range, and they are the ones that know their products best. The idea is that, even if it is the more stable app, it is not the easiest to use and it seems to need a decent mobile internet connection. The interface can be pretty confusing some times and it requires a bit of time to get used to.
