Sony Ericsson Mobile Communications has released six new phones, including a high-end, Walkman-branded handset with around 9GB of internal Flash memory, according to a company spokeswoman.
The music-centric Walkman will more than double the internal memory of previous models and will feature a newly designed media player and large-touch display for easy navigating. But, unlike Apple's planned iPhone, the new Walkman will include a keyboard.
"Our new Walkman mobile phone isn't designed as a response to the iPhone but as a further development of the Walkman," the Sony Ericsson spokeswoman said.
Sony Ericsson also unveiled the latest in its line of Cybershot camera phones, a five-megapixel device.
Several new accessories released include a global positioning system unit that can be connected to a mobile phone and new Bluetooth headsets.
