Android is a software stack for mobile devices that includes an operating system, middleware, and key applications. The Android SDK provides the tools and libraries necessary to begin developing applications that run on Android-powered devices.

This little app for your android phone does all you'd want from an SSH client. Once you've installed it from Google Market, you're ready to connect to servers all over the internet right from the comfort of your phone.

If you connect your phone to your LAN via WiFi, you can also connect to any SSH-enabled computers on the LAN.

Connecting to a server is as simple as entering the username and hostname just as you would when connecting using command-line SSH. You enter your password at a familiar looking prompt, and then you're in.

• Press and hold the 'End Call' button to bring up a couple of quick options. You can set the phone to Silent, enable Airplane mode, or just switch off.

In my view, the android operating system suffers from a few drawbacks as a phone OS.

By default the phone makes the same sound when you get new email that it does when you get a new text. For me though I want to know which it is without having to look at the screen, and fortunately you can configure this.

To change the sound that is played when a new text message arrives, open up the Messaging app, press the menu key, and then the Setings button. The notification settings can be found by scrolling right down to the bottom of that screen. You can change the ringtone and also set whether or not the phone should vibrate.

Surely changing your phone's wallpaper is the simplest thing you can do to get a look that's more your thing. The Android desktop on the Magic has three 'workspaces' by default, and when panning from one to the next, the wallpaper pans at a slower rate than any icons that are visible, creating a real 3-D foreground/background effect. A good wallpaper for the HTC Magic would take both these factors into account.
