The New York Post has put up a few more bits of info on Sony's rumored PSP phone. You guys will remember that we posted about the company getting a patent for it last week.

According to the New York Post, Sony has reportedly signed a deal with UK carrier BT Mobile. The deal includes bringing advanced multimedia communication features such as video chat and messaging to the PSP handheld system.

Analysts are also linking the PSP phone to possible moves by Sony to protect Sony Ericsson, its mobile communications arm and one of the company's few thriving departments. Apple's iPhone would be a threat to the Sony Ericsson Walkman, and coming out with a PSP phone could boost sales of both Sony Ericsson and the company's gaming division.
