After having the 3G for over a month I've loaded about 1900 songs into Itunes fror syncing to the 3G. At about 1200 songs I noticed the music was approaching 5GB used of roughly 7GB available. OK. Then something funny started to happen. Even though I have increased the number of songs on the iPhone the memory used for storage keeps shrinking - every time I sync now the memory used shrinks. I am now using 1.46 GB for my music???
