I just picked up the new iPT5 and downloaded all the app updates, including the latest Facebook mobile app from iTunes. I successfully configured and logged into both the integrated iOS 6 Facebook account and the separate mobile Facebook app. However, when I get an email that includes a link to FB, the link opens in the mobile Safari browser and asks me to (1) log into my FB account via Safari or; (2) download the FB app from the app store - which I've already installed and logged into. When I click on the link to download the FB mobile app, the app store opens and then finally realizes that I already have the app installed. At that point, the app store provides a button to "open" the app, instead of "install" it. I've looked through all the settings and I can't find a way to make the device open FB email links using the FB mobile app instead of the mobile Safari browser. I've tried re-booted the device, un-installing the FB mobile app and then re-installing it, logging in and out of the mobile app, etc. Nothing has worked. Any suggestions?
