[4] 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.

The phone is available with either CDMA technology supporting EVDO Rev 0 for network access, or GSM.

In October 2008, it released the second-generation Centro in two new colors, Olive Green and Vibrant Rose.

The GSM-based device is quad-band (850/900/1800/1900 MHz) and supports both GPRS and EDGE data protocols.

[7] PC Magazine writes: "The Centro for AT&T sacrifices the Sprint version's high-speed data access, but you get more battery life—though not quite enough.

[9] The Verizon version of the Centro, available in dark blue only, was released on June 12, 2008 for $99 with a two-year contract and a $70 mail in rebate.

[10] Good Gear Guide writes: "The first smartphone with a full QWERTY keyboard to be sold in Australia on pre-paid".

[11] Rogers Wireless (Canada) announced that it would be carrying the Palm Centro as of June 10, 2008.

As of February 2, 2009, a CDMA version of the Palm Centro in Midnight Black was released on the Bell Mobility network.

[14] In December 2008, Palm created a holiday advertising campaign, introducing a new version of Santa Claus, called "Claus", and complemented the TV spots with a Facebook page, viral videos and original music in download form.
