title: iPhone Programming: Data not coming into App on iPhone 4 running 5.1.1 on AT&T only
body: <p>Need Help Immediately!</p>
  
  <p>We have an app that has been approved, but we are getting reports that users with an iPhone 4, running 5.1.1 on AT&amp;T are not getting data showing in their application.</p>
  
  <p>Another strange thing is that if I connect using Verizon Mi-Fi, it works, but if I connect using an AT&amp;T mi-fi, it doesn't work.</p>
  
  <p>We have tested the following and have verified that it works on the following:</p>
  
  <blockquote>
    <p>iPhone 4S, 5.1.1 on AT&amp;T, Wi-Fi
    iPad 2, 5.1.1 on AT&amp;T 3G, Wi-Fi
    iPhone 4, 5.1.1 on Verizon, Wi-Fi
    iPhone 4, 5.1.1 on Sprint, Wi-Fi
    iPhone 4S, 5.1.1 on Verizon, Wi-Fi</p>
  </blockquote>
  
  <p>The devices aren't jailbroken or unlocked and came straight from AT&amp;T. Also, the information that is coming from our server is a JSON payload.</p>
  
  <p>If you need any more information or you heard of this problem before, please let me know. We really need help on this.</p>
  
  <p>Thanks!!!</p>
