While BlackBerry mobile devices and iTunes do not work together by default, they can be used through the BlackBerry Media Sync program. This software is available at the BlackBerry site and allows you to seamlessly transfer music from your iTunes program to your BlackBerry device. In order to transfer specific songs you must first have them in a playlist, otherwise the Media Sync program will select random songs and create a playlist for them.
It is not possible to use iTunes App Store apps on a Blackberry device. Apps from the iTunes App Store are only compatible with Apple's iPhones and iPod Touches. Some developers create versions of their iPhone / iPod Touch apps for other devices (like Blackberry and Android); if there is an app you are interested in, check with the app's developer to see if the app is offered on your platform of choice.
