Palm Centro
The Palm Centro is a smartphone marketed by Palm, Inc. beginning its release on October 14, 2007, offering the functionality of the larger Treo 755p in a smaller size.
The Centro is one of the last devices to run the Palm OS operating system. The successor to Palm OS is webOS, which debuted on the Palm Pre in June 2009.
Currently, the Centro still works with some carriers, but not with others. 2G GSM devices, such as the AT&T Centro, can no longer connect to the AT&T network. Verizon's and Sprint's 3G CDMA networks have also shut down in 2022, so CDMA Centro devices will only work offline.
With a weight of 119 g, and dimensions of 4.2″ (h), 2.1″ (w) and 0.7″ (d), the Centro was the smallest-ever Palm smartphone at the time of its introduction. It includes a 1.3-megapixel digital camera with video capture capabilities, microSD card slot (officially supporting up to 8 GB microSD cards, though in practice, microSD cards up to 64 GB work), 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.
An AC travel charger and a USB data cable are Included with the phone.
Palm has more recently upgraded the available memory from 64 MB to 128 MB, but the updated models were available only with Sprint.
The Palm Centro also had support for (Java) MIDP 2.0, though Palm has discontinued distributing it for licensing reasons.
The product SKU on this model was PTR690HK, which is aligned with products in the Trēo family of Palm smartphones. The Verizon Wireless SKU was CENTRO690P.
