What's a good *free* 21 Software d/l for Windows Mobile Phone?

For obvious reasons I wish I had a Berry, but currently use a Motorola Q9c (running windows mobile v.6 I believe). What's a good free software download to install on my windows mobile phone? Just something to kill the time and keep the count :) Thanks to anyone who can offer insight!

p.s. I own CVBJ v.5 on my pc and love it!
