How can i create a mobile application server?

Server Error in '/' Application. ????? I m trying to log on the T-mobile website and this is what comes up?

• What does this mean? And how can i fix it? Its not the website because i can log on with my husbands computer. Server Error in '/' Application. --------------------------------------… Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off". <!-- Web.Config Configuration File --> <configuration> <system.web> <customErrors mode="Off"/> </system.web> </configuration> Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL. <!-- Web.Config Configuration File --> <configuration> <system.web> <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/> </system.web> </configuration>

• Answer:

  Your assumption that "Its not the website" is wrong. That is most *definitely* a problem with the web site. I can't explain why you can log in with your husbands computer and not yours. Only the Geeks at T-Mobile can do that. You could try closing your browser and trying again. Or you could wait a day or 2 and see if the problem goes away. But if that doesn't work, call TMO. There is *no excuse* for them posting an error message like that. One last thing: Are you *certain* you are using the same URL (web address...what you type in the address bar) on your computer that you use on your husbands? Maybe you are getting spoofed into visiting a site that has a similar name to TMO? But isn't TMO? They shouldn't ever display an error message like that...but some site trying to imitate them might.
