iPhone memory full, not sure why

[joel-simkhai]

There is something taking up all the memory of my iPhone and I have no idea what it is.
In iTunes it is labeled as "Other"
How can I find out what data is taking up all that space?

Thanks

Video? Podcasts? You can kind of rule out music, applications, photos. What have you got on it? Use anything like datacase?
