dynamicv said:Before you buy anything remember that the UK uses a mix of GSM 900 and GSM 1800, whereas the USA is on GSM 1900. So the phone you get needs to be labelled as "tri-band", or it won't work when you get back home.
True, but I'm not sure if the CDMA standard in the US is the same as the one here in Europe (known as 3G). Most GSM phones in this country are dual-band (900/1800) so definitely won't work in the US.evoluzione said:most GSM phones in the States are actually 900/1800/1900 now, but not all. of course some carriers don't use GSM at all, they use CDMA.

I was told previously that 3G was CDMA, but obviously by someone who didn't know much about the subject. Thanks for the correction.bigandy said:3G isn't CDMA. It's UTMS. there is a 3G equivalent to UTMS, called CDMA2000 (ooh, catchy), but it's currently US only (and very limited at that). While CDMA2000 is a kind of bolt on update to CDMAone, UTMS is a completely new system, thats backward compatible with GSM/GPRS based networks- the reason for this backward compatibility is that normal calls are carried over these existing networks, while 3G services, such as uprated data and video calls are made using the new infrastructures.
I know AT&T changed their network from whatever they used (I think 900 or 1800) to 850 a little while before the Cingular purchase, so they sent a new phone "upgrade" to all T68i users. Hmm, no Bluetooth, crappier screen, feels like it cost $5 to make the case. This is an upgrade how?spacepower7 said:In the US, I have seen three different types of GSM phones:
And that's just 3 different Nokia's that I have had in the past year
The are many different online resources to unlock your phone (which is legal.)
A good (if expensive option) would be the Nokia N80IDANNY said:Is their any cell phone I should get while I am their. That I cant get here.
http://www.allaboutsymbian.com/features/item/Nokia_N80_Review.php"The N80 is the first smartphone that can be truly described as a modern world phone. With quad band GSM (850/900/1800/1900) and either 1900 (US) or 2100 (Europe) WCDMA radios, it will work almost anywhere in the world. The dual band WCDMA means the N80 will almost certainly be making an appearance in the USA (on Cingular) which up until recently has had few S60 devices widely available. Data is well provided for with 3G (384 kbps), EDGE (236 kbps) and GPRS making up the cellular options and WLAN (802.11g) providing a further option. As on the Nokia 9500 and 9300i WLAN works like any other connection and can be used for browsing, e-mail or any other network connection application. Software built into the phone allows you to scan for and connect to any available hotspot. The WLAN is used for the UPnP support which we discuss further below."
You guys are both right. UMTS does indeed use CDMA technology, which is the nuts and bolts behind the system, but IS-95 or cdma2000 cell phones (offered by Sprint and Verizon in the US) use a different flavor of CDMA, so that they are not compatible with European style 3G networks.dynamicv said:I was told previously that 3G was CDMA, but obviously by someone who didn't know much about the subject.

We are, largely because European governments have outlawed non-european standards for mobiles.oingoboingo said:The US might well be the odd man out here. At least here in Australia, the European mobile phone standards predominate.
