There won't be any proof. Don't be that naive. All you need to use is common sense. Apple does not release information about what apps they reject. It would be very bad publicity. Furthermore, it is against the SDK agreement to publicly disclose why your app was rejected. Many small companies will do this, but not large corporations.
so you have no facts. as i stated, your argument is based on your assumptions and opinions. google would have said if they had rejected it, other companies have done before. PLUS you have totally ignored the articles i linked to where GOOGLE have explicitly said that THEY ARE NOT MAKING IT FOR THE IPHONE!!!! and Swype have said in June that they are still developing it, ergo it's not been submitted yet, as you cannot submit a half developed app to be reviewed........
