xx channel/xx chord ringtones?

[blueshift]

What are 16channel and 40chord(for example) polyphonic ringtones?
SE phones shows they have 40 chord ringtones. What do all these mean?

Is SEk320i available in India? I would have opted for LGC2500 but i heard its battery gets exhausted quickly.

a channel is a slot to accomodate an instrument. 16 channels means 16 different instruments can be played together. 40 means 40 different instruments can be played meaning more better output.
