The Palm Treo Pro is a combination PDA/cell phone offered in both GSM and CDMA. It is Palm's fourth Windows Mobile Treo. It replaced the short-lived Sprint Treo 800w.
The phone originally was released in an unlocked GSM format. The updated release of the phone for CDMA networks featured new hardware specifications including a more powerful processor, more storage, and less user-available RAM.
The Treo Pro supports A2DP, which allows the user to stream music to a supported device wirelessly over Bluetooth. In addition the device comes with a 3.5mm standard headphone jack. The GSM version of the phone comes packed with a stereo-headset, while the CDMA phone does not. The battery is removable.
The touchscreen is flush with the surface of the phone, a first in the Palm line of products. The full QWERTY keyboard is in the same style as that of the Palm Centro, with a textured, rubberized feel. It is roughly 10% wider than the Centro's keyboard.
The familiar ringer switch is located, as expected, on the top of the device. It switches the phone from having sounds on to a vibrate only mode instantly.
Vodafone (UK) was the first carrier to officially use the Treo Pro. Also: Telstra (Australia) & Telecom NZ (from May 2009) although the phone is available unlocked as well. M1 (Singapore) began selling the Treo Pro in 2010.
Bell Mobility & Telus in Canada, and Alltel and Sprint Nextel in the US, picked up the Treo Pro in March 2009. The device could also be purchased at list price (about $450) and used on Verizon's network in the US.
