iPhone features everywhere in rivals' new phones

Copying a few pages from the playbook of Apple Inc's iPhone strategy, which brings many of the powers of the Internet to mobile phones, is no way to beat the computer interloper at its game.

But that's exactly what many of the world's biggest handsets makers are trying to do with new copycat phones and services that ape key features of the iPhone.

At Mobile World Congress in Barcelona, the world's biggest annual trade show for the wireless industry, Apple is everywhere and nowhere. The company avoids such events, preferring to unveil products at its own venues.
