Palm has released the Centro Smartphone (not sure if that’s pronounced “chentro” or “sentro”). The Palm Centro “gives you voice, text, IM, email and web”. Includes Bluetooth, but not WiFi. Uses the Blazer web browser.
Probably not an iPhone killer but might be useful if you need something to use while waiting around for the iPhone to come to your country. Assuming you’re somewhere that has Sprint coverage of course.
