title: Not able to install IPA from a developer
body: <p>I have hired an iphone developer overseas to develop and iphone app for me. The dev sent me the IPA. I tried installing it using iFunBox and even using IPA installer and it keeps failing. I even tried iTunes and it kept failing. I tried it on both jailbroken and none-jailbroken devices</p>
  
  <p>The developer is telling me that he can see it on it has to go on the developer account and he is requesting the dev account credential
  My questions are:</p>
  
  <p>1- Why do you think the IPA is not getting installed properly (I was able to install different apps IPA so I know my installers work!).</p>
  
  <p>2- Is giving the dev account credential the norm?   I come from android development and for us, you give a signed APK with the user keystore and your are done!</p>
  
  <p>Please assist
  Thank you</p>
