Android Market Upload APK file hangs

I've been trying to upload an APK file to the Android Market for a few days, and the upload process hangs with the spinning icon just rotating. I've let the upload run overnight and it still hangs.

1) The APK file is 28 MB

2) I've uploaded an APK file to the Android market before and i开发者_JS百科t is now for sale.

Is there a way to find out what the error is?

suggests a 25MB limit. Perhaps temporarily strip some data from the .apk and try again?

My first suggestion would be to try a different browser. Sometimes I'll have upload issues (not with the market specifically, I have yet to upload an app) with a browser, and using a different one usually works.
