I have just encountered very str开发者_JAVA百科ange problem - my GWT app hosted on Google App Engine does not want to work on iPhone over 3G, however it works fine over Wi-Fi.
For testing I created empty GWT module with only Window.alert in the onModuleLoad. If I switch on Wi-Fi, the alert is shown, with 3G - just blank page although with correct title.
Safari Developer console on iPhone looks absolutely the same for 3G and Wi-Fi - some 3 errors about wrong placement of meta tags.
Just recently I installed iPhone OS 4.0 (tried beta 1 and beta 2), and I can not roll it back to version 3, so can not really say where the problem is.
Does anyone have any ideas what may be happening here?

This was not a problem neither in iPhone OS 4 nor 3G. Looks like something wrong with Google AppSpot. Now it works well.
