In putting on homebrew apps I did something wrong and had to restore my phone. I was surprised, because of what I read about other experiences, that my contacts restored with pictures attached as well as all my pictures that I put on my phone or took with my phone restored. Also my mp3s restored. My Classic programs that I had put on there did not, and so I have to put those back on myself. Had to redo the homebrew apps, but did it right this time. So minor customizations gone, but for the most part it all restored just fine. Thought I would share my experience since it was a smooth one. Love the Pre!
