Gmail introduced its new Gmail for Mobile web app for Andriod, iPhone, and iPod touch. They have tweaked the interface to allow for easier searching and basic archive, delete, etc. functions, but the most interesting update is that the app allows for offline reading of recently read messages using Gears for Andriod and SQLite for iPhone (according to Engadget). It was an allover great experience for me when I tried it out, and as earned a home screen icon on my iPhone. Check out their video (and TUAW’s review)for a demo and more information:
They also updated Google Calendar for mobile, looks like they are doing some good stuff on the mobile front.
