Can anyone confirm that an administrator cannot use the iPhone NetSuite app? Thank you.

From the help:

Why am I unable to log in with my Administrator role?

If you require NetSuite access from a mobile device using a non-standard role, you need to add the Mobile Device Access permission to this role. This permission can be added to the System Administrator and customized roles. This permission cannot be added to the Administrator role.
If you are an administrator and require mobile access for the Administrator role, you can assign yourself a custom role that has mobile access enabled.

Thanks, this is my reference too. I just don't want to believe that they don't allow an Admin to have access. Lol

No admin access via mobile

Thanks for the confirmations.
