I noticed that Good Reader supported this in their last update, and couldn't figure out what it is - so i went hunting on Google. I stink at searching - but I finally found an article that talked about it. (in case you were clueless like me) Basically, in mail - tap and hold on an attachment and you can pick what app to open it in. I had to put my email on the kids iPad last night to try it - and it worked! LOL!! Which is cool. How much can be done with this? What Apps register themselves as targets? (the Eurosmartz products would be nice) I haven't come across anyone talking about it - but granted, i haven't been HOME the last week either. And i'm walking out the door in a few for early morning Orientation Flights at the airport.
