Android is well known for its openness. As the owner you can choose how you want to use your device, and you can pick the way you like to install your apps.
So, you can go to Android’s settings / applications, enable the checkbox “install from unknown sources” and from now on you’re free to download any “.APK” app setup packages from the web and install them directly onto your device.

Now you can simply use an app called “sideload” to install apps onto your phone, even if it’s locked by AT&T. Here’s a quick tutorial on how to use “sideload”:
