Mobile iphone cache

Hi, I’m not sure if this is a WP3 Total Cache issue, but for some odd reason my site shows our long deleted “Coming Soon” page on our mobile phones. Funny thing, the page does not appear on an ipad, laptop or desktop. I’ve tried clearing the cache on the phone with no luck. I even asked others to see if they have the same experience on their phones, and they too see the coming soon page even after clearing their cache. I even tried different browsers as well.

Any idea what’s causing the page to show.

FYI the “Coming Soon” page was deleted months ago.
