Unable to download .mobileConfig on iPhone

I've created a configuration profile using the iPhone Configuration Utility which I've placed on a server and enabled the MIME Type for .mobileconfig as application/x-apple-aspen-config. The URL to the profile is something like http://xxx.xxx.xxx.xxx/DeviceProfile.mobileconfig

Now when I try downloading the file开发者_JAVA百科 through Safari, I get the error as Safari could not open the page because the server stopped responding

I'm able to download the file on any computer and also on a Nokia phone. When I try opening the URL in simulator, the spinner in the status bar (3G connectivity) keeps rotating and I get no error message.

Please note that I'm using iPhone 3G with iOS 4.2.1

1. Set security as "Always"
2. Remove all passwords from settings.

Try installing once. If you are able to download, it means there is some problem with the password of the security.
