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 3.5 mm 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^[4]) although the phone is available unlocked as well. M1 (Singapore) began selling the Treo Pro in 2010.^[5]

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.
