A colleague recently asked me the following:
I recently moved from the UK to the US. When I tried to sync my music, iTunes wiped out all my music on my iPad. Instead of copying the music from my iPad to my computer, it removed all the songs off my iPad. What can I do with my other iPad that has my music collection so I don't lose it?
