How to create an iPhone app

Those who have given into the marketing hype of the iPhone may well have found that, despite having thousands of apps available in the App Store, the one you really want doesn’t exist. Creating your own app will provide the functionality you need, and companies who do so stand to gain real kudos. We'll also show BlackBerry and Google Android users how to customise their handsets.

Create a custom BlackBerry theme

Step 1. Downloadable apps let you customise your handset. As well as the widgets for Android below, you can make some pretty radical changes to the look and behaviour of a BlackBerry handset with BlackBerry Theme Builder Studio. Launch the program and specify your handset.

Step 2. Choose between three layouts: Zen, Today or Custom. We’ve chosen Zen. The Inspector palette lets you customise various elements, from the colours indicating callers in your contact book to the wallpaper and button icons. You can’t save custom colours, so note down the RGB values if you want to reuse a shade.

Step 3. You can import your own photos for use as backgrounds on the main caller screen or to superimpose on the button showing an incoming call, although you may need to resize them first. If you want to offer your theme via the BlackBerry AppWorld, you’ll need to own the copyright for any elements you include.

Step 4. You can add icons and buttons to the theme. You can make your own and save them as PNG image files or SWF animations.
