It's the mobile everybody's talking about. T-Mobile's new G1 is the first Android phone available in the UK.

Android is a revolutionary new and easy-to-use mobile operating system backed by Google that enables you to download applications and access the internet on the go far easier than ever before. But the G1 revolution isn't just about Android, here are 10 more great reasons why it's the phone to watch.

1 The latest tech
The G1 is truly cutting edge, featuring the very latest in connectivity options with built-in Wi-Fi and high-speed 3G/HSDPA for mobile internet access as well as a built-in GPS receiver for tracking your current location.

2 Easy to touch
As well as having a brand new interface, the G1 has a full touchscreen and easy finger navigation. Using it one-handed? Then there's also a convenient trackball you can use, too.

3 The latest Google apps
Android is backed by the mighty Google, so you'll get the latest Google services such as Google Mail and Calendar. There's even one-touch access to Google Web Search. Built-in support for YouTube enables you to easily search for and view videos via a special application on your phone.

4 The easiest input
The G1 has a hinged touchscreen that slides open to reveal a full QWERTY keyboard - you won't miss a letter when you type your texts and emails even when you're on the move. No dodgy letter touches or keypad presses.

5 Best-ever mobile maps
As well as Google Maps with its satellite and map views, you also get built-in location-based GPS, so you can find out where you are in an instant. The G1 also supports Google Maps Street View – enabling you to view online images of your surroundings and navigate 360 degrees just by rotating the phone around you with your hand! The UK isn't supported yet, but you can check out street level in major US cities and Paris right now.
