The 755p is Palm's highest-end Palm OS smartphone for CDMA/EV-DO carriers, which include Alltel, it's soon-to-be parent company Verizon wireless, and Sprint in the U.S.

As with other recent Treos, the 755p loses earlier models' external antenna for an internal type. It also has a QWERTY thumb-keyboard and a high-resolution 320 x 320 pixel resolution touch display.

The smartphone is 3G-enabled through support for CDMA operators' EV-DO (Evolution Data Optimized network) cellular-wireless networks. This high-speed technology carries content - video, e-mail, pictures, etc. - at average rates of 400 to 700 kilobits per second.

Specifications for the 755p include a 312 MHz XScale processor, 128MB of non-volatile RAM (60 MB user available), a miniSD memory card slot for up to 4 GB of additional storage, a 1.3 megapixel camera for picture and video, a 1600mAh Li-Ion battery, and Bluetooth.

You may use the 755p as a modem for a laptop to connect to the Internet or enterprise through a wireless Bluetooth or wired USB connection.

The 755p was Palm's first Palm OS Treo to offer built-in e-mail support for Microsoft's Direct Push technology through the device's VersaMail application.

Google Maps for directions, local searches, moveable/scalable maps, satellite imagery, and traffic updates is built right into the 755p's ROM.

Palm also bundles its threaded SMS/MMS application (something similar was just shipped with Apple's iPhone), which allows you to view messages in a single chat view. You surf the Web through the Netfront browser from ACCESS and read/edit native Microsoft Office and PDF files through DataViz's Documents To Go Version 8.
