Amazon has approved almost all of my apps for their App Store but all apps go through a separate review process for Kindle. Amazon has declined to add almost every app to the Kindle store citing “app will not install”. Because of this extremely detailed explanation, I will not be adding my apps to Kindle until they can communicate a little better to specifically state what the issue is.
As for Blackberry, they have indicated only 4 issues (very detailed and specific) with the apps, which I am hoping can be addressed in the very near future. This is, however, entirely up to my hosting service to determine if they’ll incorporate the changes Blackberry requested they make.
