Palm has finally unveiled the Treo 750. Although you won’t be able to purchase the device until “late January 2007″, you can still visit Palm.com for complete specs and details. Much like the Treo 680, the 750 is sans external antenna but sports twice the memory (128MB), Windows Mobile, and UMTS (high speed internet) compatibility. Unfortunately, the device is launching on Cingular, and since it lacks HSDPA (Cingular’s high speed network) it means you’ll be stuck with Cingular’s antiquated and slow EDGE network.
