I apologise - I made a mistake regarding the iPhone/iPad and Android versions of the Okawix release. These are not yet out, but should be available soon. In the meantime, you can help with beta testing http://blog.wikiwix.com/en/2011/03/09/version-beta-dokawix-pour-android-ipho...
Sorry about the error,
