After helping all of you out for the last 2 years and a bit, it is my turn to ask for some help.

I got a Blackberry about 2 weeks ago and have only put one song on it so far (which is only 90 seconds long... a snippet) and when I've tried putting a second song on (a regular 4 minute song), it is saying that there is "not enough space on the disk". A few questions.

1. What is "the disk"?
2. Why is my blackberry only letting me have 1 song?
3. How can I clear space for another song? (I've already deleted all my internet history on it and messages.)
