How Do I Know what "Other" Means?

[Radioguy2010]

I see in iTunes that 2.91 GB are taken up in my phone with "other." Is there a way to figure out exactly what the "other" is? Is it books in my reader? Newspaper articles saved in Instapaper? Documents stores somewhere? I don't read the books all that much, but I don't want to junk all of them either. Many thanks.

That's a HUGE amount of other and almost sounds like you got some corruption somewhere. However, I don't have books or download newspaper articles in instapaper. Do you have that much for those? FYI, other is normally around 300 MB or less.
