Google (GOOG) has created a special version of its Gmail e-mail service that provides mobile phone subscribers with quick access to their e-mail, the company said on Friday.

Details on the mobile e-mail service, which currently is only available to U.S. cellphone users at http://m.gmail.com.

The service works on the subset of more advanced mobile phones that offer an Internet browser. Users can view attached photos and documents from their phone, and reply-by-call to people whose phone number is stored in their Gmail account.

Gmail messages are automatically synchronized between their mobile phones and computer accounts, regardless of whether Gmail is accessed from Gmail Mobile or the Web.
