If you don't currently have an app for cross-platform messaging, or maybe you're looking for something new to try, eBuddy XMS has a lot of features you might enjoy. XMS users in your phone book are automatically added to your XMS contact list, and you can link your Facebook account to find more friends. Messages also have sent and read indicators, (a la BBM) so you always know the status of your message. And since the messages are sent via your internet connection, you don't have to worry about texting overages or extra fees. You can find eBuddy XMS in BlackBerry App World for free at the link below, and for other platforms simply visit ebuddyxms.com.
