The Palm Treo Pro sporting Windows Mobile Professional 6.1 alongside the Palm Centro using Palm OS Garnet. Both devices show Sprint branding.

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.


GSM: Vodafone (UK), Telstra (Australia)[edit]

Vodafone (UK) was the first carrier to officially use the Treo Pro. Also: Telstra (Australia) & Telecom NZ (from May 2009[5]) although the phone is available unlocked as well. M1 (Singapore) began selling the Treo Pro in 2010.[6]

CDMA: Bell Mobility & Telus (Canada), Alltel, Sprint Nextel (US)[edit]

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.
