Research In Motion(s rimm) took the final wraps off of a software update for BlackBerry Messenger 7 on Monday, adding voice calls over Wi-Fi to the popular messaging service. The calling feature was previously announced while in beta testing, but becomes available to the general public today in the BlackBerry App World store.
The new feature should be especially useful in areas with high wireless network concentration and in regions where voice calling minutes are still expensive.
I really like this concept. I wonder if it works without a carrier plan. In other words, get a supported BB for full price and you are good to go for UNLIMITED VOWIFi as long as you can have access to WIFI.
