According to research by Strategy Analytics, a market research company, over 90 percent of feature phone owners in the US and UK are interested in downloading and installing applications such as SNS (Social Networking Service), IM(Instant Messenger), VoIP (Voice over Internet Protocol), and navigation and mapping.
Other IM programs don't require that--users of AOL InstantMessenger, for instance, might have a totally different IM name than their e-mail address, or might not even have an AOL account at all.
