Sony Ericsson T608

I recently inquired to sprintpcs to see if they were coming out with any bluetooth phone in the near future and was told that yes they have 4 new phones coming out today Dec 4 , 2004 ! the sony ericsson t608, palm one treo 650, lg pm 325, and pcs pp-660. But now I have found out that the sonyericsson had been out for over a year but never marketed to the general public. So i am just wondering if this phone has had a software upgrade and battery problem fixed and does the bluetooth work well? I may try it and see what happens anyway. I also have the new sanyo mm 7400 and it is the most advanced phone to date that i have ever seen. All this phone needs is bluetooth. Anyway, let hope that sanyo makes a bluetooth phone for sprint ASAP.
