The scoop

Motorola's first Android phone takes advantage of the company's MotoBLUR user interface. Motorola has bet its continued success on Android, and is seeking to get wide distribution for the Cliq, which will be sold overseas by Orange in the UK and France, Telefonica Spain, and American Movil in Latin America. Sprint's first Android phone is also HTC's first to sport the company's proprietary Sense UI, which allows users to put a contact's photo alongside their text messages, emails and call history in a single view. The UI also allows users to set up customizable push widgets for things like Twitter feeds, weather and email. The Pixi, Palm's second webOS device after the Pre, has been positioned as more compact and affordable device than the Pre. Palm also is emphasizing that the phone's casing can be customized, something that may appeal to a younger demographic less concerned with productivity applications.  HTC's latest Windows Mobile phone is the successor to its popular Touch Pro model. The gadget has attracted wide carrier support and features new HTC innovations such as Push Internet and Straight Talk, which allows users to set up  multi-party conference calls by accessing contact information in their email inbox.
