Well the British Library are all set to drive mobile fans wild with a range of animal noises.
The massive library is letting 40 of its best animal sounds it has in storage be used as ring tones.
Relaxing
There are penguins, pig grunts, and all sorts of exotic animals and birds.
Bosses there have sold the ring tones to two companies who will sell the sounds onto their customers.
They reckon they'll make a nice change from the usual beeps and pop songs that most people have.
And they hope mobile users will find them fun and relaxing.
They'll be available from September 2003 on new polyphonic mobiles.
