I upgraded to the 3GS from an unlocked and jailbroken 2G iphone. I had done some customization on my old iphone, including themes, SBS settings, as well as using the "categories" app to hide some apps that I don't use that often. Among the hidden apps, notes was one of them. When I got my new iPhone, i plugged it into itunes, and restored it from the last backup I had made. After the sync was complete, I noticed that the notes app was gone! It doesn't even come up in a spotlight search! Not a huge deal for me, because I never used it, but interesting nonetheless. Also, I had several "blanks" in my old phone - generated by a program called iBlank - which were essentially transparent icons that linked to a dead page in safari. These allowed me to arrange the icons in interesting ways. Anyways, these carried over too. Just wanted to share and see if anyone else has seen the same thing.
