Sony refuses PlayStation brand for PSP Phone?

[Maximus]

I should make clear, that's not to say there won't be a PSPhone, it just won't be a SE made phone. It will be designed by SCE and be properly integrated into the PS family.

Talks atm are saying PSP2 and PSPhone will be similar, PSPhone must be able to play all downloadable games, while PSP2 can play full retail games. That was the word recently.
