I have developed a phonegap application which is running absolutely fine on iPhone. Now, I want to submit the app to the appstore. Following is the procedure I am following
I resolved this by simply removing the "binary" file(s) in the error.
For you its www/js/release.sh.
For me it was two redundant bower-files, a .sh-file and a .js-file that was located under a "bin"-folder (maybe thats why it thought it was a binary?).
On a side-note, it seems that you could still continue the upload process by just clicking Send after being presented with the errors in Application Loader.
