Google Android users can now configure the Gmail app to only synchronize the most important messages to save on bandwidth and power consumption. All you need is the new Gmail 2.3.5 app from the Android Market and the Priority Inbox feature which automatically detects the messages you’re most likely to want to see, based on your past behavior.
Another new feature is the ability to assign different ringtones for each Gmail label or filter.
Gmail 2.3.5 can also remember whether or not you want to show pictures in messages from a specific sender, or turn of sticky message actions in landscape mode or in both landscape and portrait mode.
You can download the updated Gmail app from the Android Market. It will replace the app already on your phone.
