Yeah… I should post this article long time ago. HTC HD2 has lot of custom Android ROMs. But I don’t like most of the ringtones that come along. So how to create custom ringtones, alarms, and notification sounds for Android? The task is as simple as ABC by using Ringdroid. It is an Android application for editing and creating your own ringtones, alarms, and notification sounds. And supports MP3, AAC/MP4, WAV and 3GPP/AMR file formats.
