Check GSM World - the website of the GSM Association for your country, or check the link that is offered from the homepage on the 8830's browser.

BTW, I've only gone as far as San Juan with my 8830, and it took a huge steaming dump when I got there. Voice only; if I activated data, I got a looping device reset.
