- In most countries, the Global System for Mobiles (GSM) is the dominant cellular (mobile) telephone technology used, usually at 900MHz, however a number of networks have added 1800MHz in recent years, to boost network capacity... Dual-band handsets are pretty much standard these days, to cover both frequencies.
In North America and Canada, 1900MHz is the dominant GSM frequency, however like with the rest of the world, a second frequency (850MHz) has been added to boost network capacity... Again, dual-band handsets are widely available to take advantage of this.
Therefore, you could say it's GSM 850/1900 for North America/Canada, and GSM 900/1800 for most of the remaining countries...
Whilst GSM is still by far the dominant cellular (mobile) telephone technology in use globally, outside of North America and Canada, most countries are in the process of or have already ditched GSM in favor of newer 3G (third-generation) networks, usually using WCDMA as the technology of choice - 2100MHz is most common, however a small number of networks use 850MHz instead (off the top-of-my-head, one network in Australia and some networks in North America/Canada).
A small number of countries (Japan and North Korea in particular) use technologies and/or frequencies not supported by the rest of the Developed World...

- If you're happy to read a bit, GSM World has extensive information on global cellular (mobile) telephone networks, detailing the technologies and frequencies used in almost every country (it's under their "roaming" section):
