Wireless service provider VoiceStream has released some additional details about the high-speed phone service it will call "iStream," which may be launched by year's end.
According to the VoiceStream Web site, the service will offer "PingPong," which will let consumers send 140-character text messages between cell phones. Downloadable ring tones, such as the theme from "The Simpsons" will also be marketed. A description of the rate plans are also available by visiting VoiceStream. --Ben Charny, ZDNet News
