Yes
Large international companies like Apple and Nokia usually sell quad band mobile phones, because quad band mobile phones can be used everywhere in the world.
yes your UK nokia 6300 will work in u.s just you have to make sure that it is quad band. There are phones which support only three bands or frequencies so it may not work in certain areas but a quad band gsm phone will work in almost anywhere. or you can check on this further here http://areacellphone.com
Only if it unlocked and support Quad band GSM 850/900/1800/1900.
yes, the tri-band feature very well allows it to function.
Europe and Asia use dual-band through quad-band phones that are at the minimum able to operate in the GSM 900 and/or 1800 frequency bands. In North America (at least those that are carrier-based) are predominantly only dual-band phones, are in GSM or CDMA bands, and are SIM-locked.
The i850 has neither. Quad Band refers to GSM phones that carry radios that can communicate on any of the four globally used bandwidths (850/900/1800/1900). Nextel uses IDEN radios, not GSM, so the technology is not interoperable with GSM Phones.
Yes it will. you need to make sure it is unlocked and a quad-band. in your case you should be good as long as it is unlocked
Basically, the difference lie on the frequency being used or supported. For GSM dual band phones, the frequencies that is can support are 900/1800 MHz or 850/1900 MHz; for tri-band phones, the frequencies are 850/1900/2100 or 850/1700/2100 or 900/1900/2100 MHz or 900/AWS/2100; and for quad-band phones, the frequencies are 850 / 900 / 1800 / 1900

The Nokia N95 is a 3G dumbphone. It supports 2G networks on the 850, 900, 1800 and 1900 MHz bands, and 3G HDSPA on the 2100 MHz band for the international version, and on the 850 and 1900 MHz bands in the American version.
