There's a big new version for Gmail's Java application for mobile phones, released quietly yesterday. If you click on a contact in Gmail Mobile 1.5, you'll see full details, including their photo, and if you entered the phone number in your contact's details, you can call them directly from Gmail Mobile. More improvements listed below.

Another improvement is that you can save an unfinished message for sending it later. And, like the Maps Mobile application, Gmail shows the bandwidth usage every time it loads data. Plus there's an option for encrypting your traffic, but this is not recommended because it slows down the application.

It's early days for Google Mail Mobile 1.5 and note that so far it's available only in English.

To install it, visit gmail.com/app from your smartphone.
