This is by design AFAIK. This is to stop trading music on removable media. A flashed phone is a new phone (with probably a new GUID hidding somewhere in the registry). It's just a PITA when you have a mix of RTG tracks and your own tracks. With my 16GB uSD card, it takes about 1 hour to resync ~9GB of music.
