Googlemail (its name in Europe after a trademark lawsuit) has been around since 2004, with the original selling point of a huge amount of storage, meaning you never needed to delete an email from your account. Currently, that’s 2.8GB per account. You can now freely sign up to Gmail in across Europe, the Middle East and Africa, as well as in Brazil, Australia, Russia and Japan. It’s already open in the US.
Google has also launched its email client for mobile phones in the UK, allowing you to sync your phone with your Googlemail account to send/receive email and to read mails and browse attachments.
