Along with our pal Ryan Kairer from Palm Infocenter, we hit Handspring’s big press event for the Treo 600 yesterday afternoon. Besides getting to play with a Treo 600 (which we now lust after heartily), we didn’t learn much we didn’t already know about the phone, except that there will be four carriers offering them next month: T-Mobile, Cingular, AT&T Wireless, and Sprint. Oh, and the GSM and CDMA versions look about the same, with the GSM version having a silvery finish, and the CDMA version having a dark grey finish.
