The Palm Centro is a smartphone that was marketed by Palm, Inc. beginning with its release on October 14, 2007, offering the functionality of the larger Treo 755p in a smaller size.
As of August 2008, the Palm Centro was the second-ranked US smartphone based on internet traffic, responsible for 78% of the traffic on Palm devices; it fell to fourth in February 2009, responsible for 86% of Palm traffic.
The Centro is among the last devices released with the Palm OS operating system, superseded by Palm's webOS, which debuted on the Palm Pre in June 2009.
At a weight of 119 g, and dimensions of 4.2″ (h), 2.1″ (w) and 0.7″ (d), the Centro was the smallest smart phone offered from Palm up to its introduction. It includes a 1.3-megapixel digital camera with video capture capabilities, microSD card slot (supporting up to 8GB microSD cards), touch screen navigation and a QWERTY keyboard. The phone is available with either CDMA technology supporting EVDO Rev 0 for network access, or GSM. The stock battery allows for up to 3.5 hours of continuous talk time. The phone also offers internet connection tethering to laptop or desktop computers.
Included with the phone is an A/C travel charger and USB data cable.
Palm has subsequently upgraded the available memory to 128 MB. The updated models are available only on Sprint.
The Palm Centro also has support for (Java) MIDP 2.0, though Palm has discontinued distributing it due to licensing.
The product on this model is PTR690HK, which is aligned with products in the Trēo family of Palm smartphones. The Verizon Wireless SKU is CENTRO690P.
The Centro runs Palm OS 5.4.9, and as a result of the backward compatibility aspects of this operating system, many applications released for previous Palm PDA/smartphones work with the Centro. This phone has been streamlined to work with many popular applications and services.
