XDA Developers being again the pioneers in this, they’ve released the WM6.5 Streaming Widget which is a custom user interface element for the upcoming Windows Mobile 6.5 operating system.
The Widget will connect to TodayPDA in order to offer you access to 7883 radio streams and 3252 television streams from 59 different countries (see the thread for a complete list) while all the streams are checked every two weeks (live, offline, removed, etc).
For those of you who are brave enough to already run custom WM6.5 ROMs (which we do not recommend!), you can find information on installing and usage on the home thread at XDA Developers.
Thanks for the tip, Maarten!
