T-Mobile launched yesterday two new applications for its G1 device. The apps are called Opera Mini and Fusion Voicemail Plus and are available for free on the Android Market.

Opera Mini 4.2 features page zooming, bookmarking, searching for in-line text and saving, which are all well known in the Mini series. The new release brings side skins (themes) and also support for video playback. The browser is available in 90 different languages, which include Amharic, Armenian, Assamese, Bengali, Gujarati, Kannada, Kirghiz, Lingala, Marathi, Malayalam, Mongolian, Oriya, Punjabi, Pashto, Sinhala, Tajik, Tamil, Telugu, Urdu, Uzbek, Khmer, Kashmiri, Lao and Turkmen.

“With Opera Mini 4.2, we are showing the world that Opera never gets complacent,” said Jon von Tetzchner, Opera Software CEO. “Our support for the Android platform helps fulfill our mission to be available on more platforms, for more devices and reach more users, anywhere in the world.”

The new browser is expected to deliver a significantly greater speed, as the system compresses the data before it is sent to the phone.

Fusion Voicemail Plus was developed by PhoneFusion and equips G1’s users with visual voicemail. The app is designed to centralize several voicemail boxes and display a visual list of all the messages. The service also provides caller ID, not taking into consideration the contact details stored on one's phonebook.

The two apps are not released exclusively for the Android: Opera Mini is available for several devices that support Java applications, while Visual Voicemail can be run on BlackBerry devices and also on Windows Mobile 5 and 6 smartphones.
