Q: In setting up ituns, all 0f my kindle books were  lost and I am not allowed to open the kindle app. How do I fix this?

iCloud doesn't sync books so you wouldn't find them in your iCloud account.  I don't use Kindle but it looks like you can redownload you purchased books from the Kindle app.  See "Book was accidentally deleted from the Kindle app" here: http://www.amazon.com/gp/help/customer/display.html/ref=help_search_1-2?ie=UTF8& nodeId=200438490&qid=1349822479&sr=1-2.
