What is the Upgrade Method to go from iBird Plus to iBird PRO?
To upgrade from iBird Plus to iBird PRO you “unlock” the features of PRO that are already in Plus. You do not download iBird PRO. Its similar to when you buy a new game level for a game you own; the icon of the game stays the same and only the contents change. This is the only way that the Apple iPhone and iPod touch allows upgrades. Therefore your icon will not change to PRO but will remain Plus. A “home” screen is provided that allows you to open any version of iBird and also buy any future iBird products.
