Google released a new Web-based version of Gmail that will provide iPhone and Android phone users with faster access to messages and offline access. “You’ll notice that it’s a lot faster when performing actions like opening an email, navigating, or searching. And if the data network drops out on you, rest assured that Gmail won’t. You’ll still be able to open recently read messages and to compose over a flaky, or non-existent, network connection,” wrote Google mobile engineer Joanne McKinley on the Google blog.
