The Tungsten T3 was the third T-Class Tungsten device. It has 64 MB of memory (52 MB usable), a 400 MHz Intel PXA261 processor, a new 3.7" 320x480 transflective TFT LCD touch-screen, and runs Palm OS version 5.2.1. It was the last product designed by the Palm engineers in Arlington Heights.
The T3 included Active Input Technology with Virtual Graffiti 2, a Virtual keyboard, and the typical Tungsten line slider. With many other additional features, the T3 was released with the same $399 retail price tag as the Tungsten T2 until the release of the Tungsten T5, when it was reduced to $349.
Like the Tungsten T and T2, the T3 still has a front-facing speaker, microphone, vibrating alarm, indicator light, and all of their other features.
Like the Tungsten E, the Tungsten T3 came with an enhanced PIM Suite which categorized all appointments and tasks on the Calendar (formerly Date Book) screen. The Enhanced PIM Software also has an improved Task suite (formerly To Do List) which can categorize Tasks by either urgency, category, etc., and an improved Contacts (formerly Address) application with picture support and more fields.
Furthermore, a new status bar always appears at the bottom of screen, giving quick access to the time, system information, home, find, menu access, alerts, Bluetooth, full-screen writing, screen rotation, and what is shown in the input area.
The Tungsten T3 comes with RealPlayer for Palm OS Handhelds (called RealOne Player for Palm OS Handhelds at the time of its release) in addition to a 3.5 mm Stereo Jack, making it a digital music player when used with a Secure Digital (SD) flash memory card.
The T3 has a bigger, non-round, 5-way navigation pad with the four application buttons placed around it in a circular fashion instead of in a row, breaking Palm's traditional application button layout. Palm went back to its more traditional layout in the Tungsten T5 and Palm TX.
The T3 has a Green/Red LED, but for some reason Palm only decided to use the green LED. Red can be used with certain programs and libraries.
The T3 also has the Palm Universal Connector and an included USB cradle. The cradle is used for both charging and synchronizing the Palm's data to a PC (software is included for Windows and Mac OS X, but with the pilot-link software, the unit synchronizes perfectly with a Unix operating system).
Early criticisms of the Tungsten T3 include it electronically damaging SD cards and its battery life (900 mA·h battery). Palm addressed the Secure Digital Card problem by releasing a Firmware Update. After the "SD Card Patch" was applied in early (by the user via a firmware patch) and later (at the manufacturing stage) releases of the Tungsten T3, no other criticisms were known to have risen from the Tungsten T3's use.
Shortly following the early 2005 release of the Tungsten T5, the Tungsten T3 was discontinued. Since the Tungsten T3 was discontinued, no Palm handhelds have included a vibrating alarm, a slider to make the device smaller, or the Palm Universal Connector.
