We have received several rumors that RIM’s updated Facebook client for BlackBerry (version 1.5) will be launching today. You may remember the screen shots that BGR showed us earlier in the week. The new Facebook version 1.5 will intergrate your Facebook contacts, calender and messages with your BlackBerry address book, calendar and inbox. If this rumor turns out to be true you should be able to download it within the next few hours. Stay tuned for an update!
