You will now see a list of
BlackBerry apps, both free and paid, that fit the overall theme regarding your selections to this point. The downloadable app for Time Mobile doesn't cost us a dime so this installation will be rather quick. Using the ball/pad, scroll down to the option for the Time Mobile App (see the left image as usual) and click as before. You will see the details for the app on display now, which you can scroll through if you wish; once you're ready to download and install, scroll back to the top, highlight Download, click the ball/pad and let App World take care of the rest. For apps requiring a reboot you will be prompted accordingly so pay attention for that.
While your app is downloading (or if you choose the My World option to see your installed apps) the following menu will be used to show you what is installed (or currently downloading, as in this example):

You will also see an upgrade available message for anything where a new version has been released as shown in the installed apps screen. Choosing an installed app with an upgrade to download pulls up a menu similar to the upper right example, but with options to upgrade or run what's already installed. In fact, choosing any installed app will give you an option to run it directly from App World if desired. If you're not in App World, of course, you can select it from the App menu like you did with App World itself. App World installations are shown under the downloaded apps submenu; however, this can be modified under the home screen preferences menu.
As an aside, if you're downloading a paid app, you will be presented with a Buy option that does everything that the free app download does, but also walks you through the payment process before downloading so as to ensure you stay legit. This will not be performed in the course of finishing this guide (for reasons pertaining to my own inherent privacy) -- but since it uses PayPal as a means to complete and process the transaction it should work much the same as making a PayPal transaction from your desktop computer.
