as you know, previously download & installing app took long time. Sometimes it seemed to stop working. Then you wanted to reset. But only you could see was apple logo forever, right? But situation has been changed with new socond gen. iPod touch. Today I was downloading & installing app 'Relax' which is 178MB. Then during installing, it seemed to stop working. I just reset. But after 30 seconds, it was back to locking screen with wallpaper. So it is proved that 2.1 or 2.1.1 have very tough for crash situation. I am very happy.
