for apps that allow textual input (like word processors), where is that data saved on the iPhone? app-specific database? .plist file? are there any simple tutorials that i can use to calm my curiosity? im not terribly new to development, but i know next to nothing about iPod dev. *i know this is prob an elementary question, but i've never actually used an iPhone/iPod Touch before... so you can understand where my curiosity is coming from.
