You bought a few apps for your iPhone / Touch from the iTunes AppStore. You installed them are now using those applications as the developer had intended you to.
But… what if the application developer decides that there is a feature they want to add or there is an issue that they have fixed. How do you know? How do you get a update to the one your using?
Developers are currently updating their apps and provide those at no additional charge. Some time off in the future, they will surely want to release a very different version that they will want to charge for – that day is not here yet and will carry some confusion about versions. We will cover that when it happens.
