It's a big day for Gmail as Google is in the midst of refreshing both the mobile web app and offline editions today.
For the mobile web app, the clear idea is to bring the HTML5 version closer in line with the much cleaner, streamlined Android version as well as the recently rebooted apps for iPhone and iPad.
Furthermore, mobile web users on these devices (or perhaps accessing from other mobile browsers on the Kindle Fire along with BlackBerry handhelds) should be able to look forward to improved integration with Google Calendar.
Users should be able to see these changes soon -- if not immediately -- as many Gmail users have already commented on Google+ about the new look.
