title: over the air ad hoc distribution "Unable to download"
body: <p>I am trying to distribute an iphone app ad hoc internally for a beta test to 3 users, myself (iphone 4) and two others (iPad 2, iphone 3G).  My device served as the development device as well.  I followed all of the Apple documentation, archived the app and prepared it for enterprise deployment.  I put it on my web server with the .plist manifest file.  To test it out, I installed it on my own device (which again, is the development device), and it worked swell.  So then I sent the link to my other 2 users, who then reported that they received a message that said they are "unable to download."  So first I thought that it might be a problem with the UDID, which it is not.  I had my user's download a UDID sender-app, and they matched up perfectly.  That was after I asked this question:
  <a href="https://stackoverflow.com/questions/7338939/what-is-the-mime-type-for-mobileprovision">What is the MIME type for .mobileprovision</a>
  in which I wanted to know the MIME type for a .mobileprovision file.  I took this info, and then also sent out a link to the provisioning profile.  Both of my test users could download and install the .mobileprovision file fine; the problem was when they again, tried to install the app.  One user got a message that said "cannot connect to server www.myserver.com" while the other one installed 80% of the app, before getting the "unable to download" message with 2 options: "retry" and "done." </p>
  
  <p>I am at a loss.  Does anybody have any ideas?  I am desperate!  Thanks in advance!</p>
