What custom sound format does IMSMS support?
IMSMS supports WMA/MP3/MIDI/WAV – MIDI/WAV files are to be enabled in Version 1.1 – you can use WMA/MP3 sound files currently. NOTE: do not use sound files longer than 5 seconds – the file plays asynchronously – which means it will play and keep playing until the sound ends. If you set a 3 minute sound file, you will end up playing the sound for 3 minutes – and repeat this for every incoming/outgoing/alerts sound you set for custom sound!
