The FCC’s just granted Handspring approval to sell both the GSM/GPRS and CDMA versions of its new Treo 600. We hadn’t realized this before, but there is actually a slight difference between the two versions. Both have the same internal specs (32MB of RAM, 144MHz processors, Palm OS 5.2.1), but the CDMA model (pictured at right) has a different casing and weighs slightly more than the GSM/GPRS Treo 600. As far as we know, Sprint is still set to carry the CDMA version this fall.
