title: Distribute iphone app for external beta - sign on behalf of customer
body: <p>My Company is building an app which we want the external customers to try out before submitting to the app store. Since in-house builds can only be distributed to employees of the company, what's the best way to get the app to beta customers without going through the app store?
  If the customer signs up for a developer or enterprise account and gives us their certificate, is it ok to sign the app on their behalf and give it to them?</p>
  
  <p>Thanks!</p>
  
  <p>Update: Number of devices is more than 100.</p>
