Designed by public/private partnership Digital Birmingham, the service will enable people with laptops, mobile phones, hand-held computers and wireless gaming devices to access information and services from the city council free of charge through BT's OpenZone network within the city centre.
Birminghamfiz will give access to Birmingham-specific information, relating to topics such as leisure, transport, news and weather.
"We are very excited about the potential for birminghamfiz," said Chris Price, director of Digital Birmingham. "It is very much a 'work in progress' and what is available now is only the tip of the iceberg. We are actively developing phase two which will include music and video clips, plus commercial aspects such as booking tickets online," he said.
