Hi I'm new to the site and this may have been previously answered but I can't seem to locate a resolve. I travel quite a bit for work and my route permits me to fly on jet blue. I have an iPhone 4 on the Verizon network and when jet blue sends the confirmation email with the check in bar code or when I down load the boarding pass my iPhone displays a blue square with a question mark. Oddly I can view the images on my iPad just not my iPhone. Any help will be greatly appreciated. Thanks
