After a successful dry run in Colorado and Massachusetts, Comcast is rolling out Universal Caller ID in Portland, Ore., in nearby areas in Washington State and in at least one additional town in Massachusetts.

At the same time, and in the same Northwest markets, the operator is introducing a mobile application for the iPhone and iPod Touch. The recently launched Comcast iPhone mobile application, or "app" for short, allows users to access services such as e-mail, voicemail, movie trailers, TV listings and more.

Comcast is at the beginning of a wide rollout of Universal Caller ID, providing it as an added free service. It initiated the service last week in several towns in Colorado and Massachusetts.

Comcast is making the application available only in markets the company has populated with set-top boxes made by either Motorola or Pace.

Universal Caller ID is an application the customer must download and install. With the feature, Comcast triple-play customers can view incoming caller information on both their TV and computer screens. The caller's name and phone number pop up in a banner on the screen, and the customer can answer the phone or select "exit" and go back to their TV show or online activity.

Comcast said it will take about a week to make Universal Caller ID available to the entire Portland/southwest Washington market.

Comcast's mobile app is also available as a free download. It gives users the ability to:

• Check Comcast e-mail and listen to home voicemail in one combined inbox.
• Read, reply, forward and compose e-mail, as well as read attachments supported by the iPhone.
• Manage voicemail messages and call logs, view voicemail in any preferred order, as well as "touch" to call.
• Forward home phone calls to the iPhone from the iPhone, view call history and manage home phone settings.
• See what's on TV tonight, tomorrow or next week, including program details.
• Watch video-on-demand movie trailers.
• Synch all universal address book contacts to an iPhone or iPod Touch, as well as the ability to add pictures to favorite contacts.
