T-Mobile and Google have collaborated and come up with the new T-Mobile G1 which is to be released in November.

The T-Mobile G1 will run on the open-source software platform Android. The impressive collaboration includes a touch-screen as well as a full QWERTY keyboard, a three mega-pixel camera. As the phone is on the Android platform, users can visit the online Android Market and choose from different applications in order to personalise the phone and make it their own.

As the phone is open-source, this means that developers will be able to create their own applications for the phone and a chosen few applications will be available for download in November when the phone is set to launch.

There are many mobile phones being hailed as iPhone killers but this newcomer has Wi-Fi and 3G with fast access buttons for all of the Google tools on the phone such as; Google Maps, Google Talk and Gmail.

Touch-screens can be fantastic for controlling your device; however, not all people are fans and this is why the T-Mobile G1 also has a keyboard and in order to make the keyboard easier to use there is a trackball fitted in the phone so scrolling will be a lot easier, more precise and will be ideally suited for one-handed navigation.

When the phone is released in November, people on contracts will be able to get it on tariffs of over £40 a month which will include unlimited net browsing. This will make for one of the best mobile phone deals but it will be unfortunate news for all those on pay as you go as they will be unable to get the phone without being on tariff.

The phone's creators have said that the main purpose of the phone, as well as making calls, is to expand the possibilities of online communication and Google are hoping that the Linux based Android open source software will one day become the dominant operating system for mobile phones.
