Q. Where can I find out more about the capabilities of my mobile phone?
A. The websites below are very good quick lookup resources for phone specs. Typically you can just type in the model in the search box on the sites and get the desired phone specs straight away.
This site displays which ringtone formats are supported under the "custom ringtones" or "music player" sections for each phone model.
This site indicates whether the phone has a music player capability for playing "true-tone", or "sample-based" music or audio files (such as an MP3 player).
Another good site containing mobile phone specifications, reviews, news and forums.
