Register Kindle account on iPad
Since Kindle Fire's selling well on the market, Kindle Content is well known to more people, and iPad users are glad to share and use some resources on iPad, but there are some problem make iPad users confusion:
1. "I purchased an iPad last night and the first thing I wanted to do was read a book on. I downloaded the Kindle app and selected a book to buy, however the only place I could download it to was my iPhone. I tried to add my iPad to my Amazon account, however they was not option for that device. I have no clue of and easy way to get the book to my iPad. I did try achieving the book, but it still will not show in my iPad kindle page. Thanks for any help."
And the correct answer from discuss apple is:
1. "Did you "activate" or maybe it is called "authorize" the application on your iPad?
Actually, from looking at the "Manage My Kindle" site on Amazon, the term is "register", which if you had accessed the Kindle store using the app on your iPad, then you were already registered."
2. Another situation is:
"The Kindle application that I use to read my Kindle books on the Mac is no longer working under Lion. It can't synchronize for some reason." from apple discussion
The solution should be:
Uninstall the Kindle App.
Go to your /Library/Application Support/ and delete the Kindle folder.
Then go to /Library/Prefrences/ and find the "com.amazon.kindle.plist.lockfile" and "com.amazon.Kindle.plist" files and delete those.
Redownload fresh copy of the Kindle App and try to login again.
This is answer so far has been tested to work, if you can't solve this problem, please go to discuss apple to ask for more info.
