A question for those of you who have purchased and use this app. Long version: Do you have to pay separately for both the iPad and iPhone versions? When I searched for it initially, I did not notice more than 1 version, and I was on my iPad when I decided to go ahead and purchase it, assuming, perhaps foolishly, that I could just load it to my phone at a later time. However when I sync my phone, it does not come up as an available app on my iTunes account, so after more looking it appears they are two separate things to buy? Short version: has anyone bought the iPad app and been able to also load it on their iPhone without paying again?
