Google has announced that its Gmail web email service will be available on mobile phones.

“To access Gmail, users simply visit http://gmail.com through the web browser on their mobile phone and sign in to their Gmail account as they would on the web. Because every mobile device is different, Gmail automatically optimizes the interface for each phone. Users can also 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, regardless of whether Gmail is accessed from a mobile device or through the web.”

Update: Meanwhile, Microsoft has announced the formation of The Windows Client Mobility Marketing Team. Says eWeek:

“While small—run by Mika Krammer, director of Windows product management, it currently consists of fewer than 20 people—the group’s existence signals a shift in thinking and emphasis toward mobile computing at the software giant.”
