A new app will be released next month at the Australian Deaf Games that will alert the deaf when there's an emergency nearby. Silent Tweets is free and goes through a special portal rather than Twitter to smart phones in Australia. The information might be about the weather, a power outage, earthquake or even just changes to a train arrival for people at a station. Silent Tweets recently won a Telstra Innovation Award. The app will work with Apple and Android phones first and later with Blackberry and Windows Phone 7. Read more about the app
