title: Passbook pass not working in iOS7 - only works in iOS6
body: <p>My passbook passes are currently working in iOS6 and not iOS7.</p>
  
  <p>I've replicated the problem in the iOS simulator. The console log from the iOS7 simulator gives me this:</p>
  
  <pre><code>Nov 13 14:10:10 XXXX.local backboardd[779] &lt;Error&gt;: __hid_dispatch_pthread_root_queue_create_block_invoke: specific=0x4d530d0 pthread_self=0xb0115000 
  Nov 13 14:10:10 XXXX.local backboardd[779] &lt;Error&gt;:__hid_dispatch_pthread_root_queue_create_block_invoke: specific=0x4d52f10 pthread_self=0xb0197000 
  Nov 13 14:10:18 XXXX.local MobileSafari[818] &lt;Warning&gt;: Invalid data error reading pass pass.xxxxxxx.xxx.xx.ticket/[barcode]. The passTypeIdentifier or teamIdentifier provided may not match your certificate, or the certificate trust chain could not be verified. 
  Nov 13 14:10:18 XXXX.local MobileSafari[818] &lt;Warning&gt;: PassBook Pass download failed: The pass cannot be read because it isn’t valid.
  </code></pre>
  
  <p>I don't think it's the  lines as I've checked the team identifier and pass type identifier and they both match what's in the dev center.</p>
  
  <p>So I think this must mean something:</p>
  
  <pre><code>__hid_dispatch_pthread_root_queue_create_block_invoke
  </code></pre>
  
  <p>Any ideas?</p>
  
  <p>The error message displayed on the screen is "Download Failed - safari cannot download the file", but I think thats just a standard message.</p>
