RIM has released Facebook for Blackberry Smartphones. Announced at the CTIA Wireless I.T. & Entertainment show in San Francisco this week, T-Mobile will be the first to utilize the software application. You can do everything that Facebook offers including sending and viewing messages, instant message notification, poking, making new friends, and uploading. You can also set a unique ringtone alert. Free to download, remember that data charges may apply. By the way, our DIY purplish Sonic was made in one of Facebook’s applications. That’s reason enough to sign up.
