More and more Android apps developed by Google are available in the Android Market. Until recently, applications like Voice Search or Gmail couldn't be installed from the Android Market. They were usually included in the firmware by phone manufacturers as part of a deal with Google.
The latest Google application added to the Android Market is Gmail. There aren't many changes: message headers are displayed at the top of the window even when you scroll down, you can click on "show quoted text" to see the text that prompted a reply and the built-in "important" label has been added to the interface.
"Gmail updates aren't tied to Android version releases anymore. Now you can get new Gmail stuff faster without having to wait for system updates," explains Google. Another advantage is that Android users will be able to install Google's apps even when companies like Verizon or Samsung pre-install applications from Google's competitors.
The update to Gmail's app can be installed if you use Android 2.2 (Froyo). Just search for "Gmail" in the marketplace or scan this QR code. Other "Google experience" applications available in the Android Market: Google Search, Voice Search, Google Maps, Street View, Google Voice.
