Review

Z610i is a seductive clamshell phone with design in mind.
The impressive external screen is discrete and not apparent until a call, message or calendar event is displayed.
Capture and share quality pictures. Picture blogging lets you have your pictures online in seconds.
Enjoy the Internet wherever you are. With 3G, you have the speed you need. RSS feeds bring live news updates straight to your inbox.
Z610i is reflective, effective and imaginative.
