Submitting application to Apple store - application failed codesign verification
<p>I tried to upload my iPhone application to the App store, but received the following error: <strong>The binary you uploaded was invalid. The icon file must be in .png format.</strong>
The icon file IS in .png format, size 57x57, so assumed it is a bug and tried to upload with Application Uploader, when I got another error:
<strong>Application failed codesign verification. The signature was invalid, or it was not signed with an Apple submission certificate.</strong></p>

<p>I followed every single step, and it is not working... it is driving me crazy! Please advise what should I do! </p>
