It was only back in September when the new version of the Android app for Gmail was launch. It meant the app was no longer tied to particular versions of Android and at the time it promised faster updates and today we see it is keeping its word.
The new version of the Gmail app brings better Priority Inbox integration, allows for sending messages from multiple accounts, in-line message response and improved message composition. The only drawback is this update is only available to those using Android 2.2 (Froyo) and of course anyone using a Nexus S and Gingerbread. This will leave quite a few Android phones, which still run 2.1, stuck with the older version of Gmail.
With the new version you get a new Priority Inbox view which includes all important messages in your inbox, regardless of whether you’ve read them or not. You can archive and delete conversations or mark them unimportant from there. You can also change a conversation’s importance using the importance markers in the menu. You can switch between inboxes or labels by tapping on the current label. Another nifty feature allows you to set your phone to notify, vibrate, or ring only when you get new 'important' mail – which will save a lot of email checking only to find out you’ve won the Belgian lotto again.
In relation to composing mails, you can now easily switch between reply, reply all, and forward while composing your response which is a lot slicker than the previous method of going through a lot of menu options. Additionally, if you have configured your desktop Gmail account to send from multiple accounts this function is now also available in the Gmail for Android 2.3.2 update. Finally in-line message responding is also available in the update.
