Question

I am dynamically generating (in a PHP script) a .mobileconfig file for iOS devices and then serve it over the web. I am delivering the file with the application/x-apple-aspen-config content type and with Content disposition as attachment;filename=myprofile.mobileconfig.

My problem is I keep getting an error that says: Safari could not install a profile due to an unknown error. What am I doing wrong? See the mobileconfig file below:

    $content =  "<?xml version=\"1.0\" encoding=\"UTF-8\"?>

I am getting this issue both in the simulator and iPhone 3G and iPhone 4 devices.

The problem is that although proxy and proxyPort are optional, if proxyPort is included and is null, as in my xml then the profile won’t install and will throw that annoying error. The solution is to remove it if it’s not necessary.
