I didn't really follow the evolutions of network standards since introduction of the GPRS.

I heard that between GPRS and UMTS, there will be alternates. Most specifically, I heard about EDGE or HSCSD?

Could anyone tell me more? Is the T610 compliant with the successor of GPRS?

Also, I remember that the US used to have another standard than GSM. Where are we standing now?
I'm planning to move to the east coast in a year or so, what can I expect to find there?

other US standard is CDMA

and the next step is 3G

for more in depth answers

u seem a little confused.

GPRS is an add-on to the GSM stucture.
UMTS (3g) will also use gprs.

The t610 will not work on a UTMS network as it is a gsm phone.

Som south American networks use another network standard called iden.

GSM data uses CSD which is circuit switched data. HSCSD is therefore High Speed CSD and fits in between CSD and GPRS (general packet radio service.

here is a comparison of these.

T610 will not be compatible with any other than these.

is that not the nokia gaming thingy?

EDGE capability as a high-speed data enhancement has begun to spread to GSM networks, with the first deployments having started at the end of 2001. Nokia has already delivered EDGE-capable GSM hardware to more than 50 operators globally and expects the markets to move rapidly to GSM/EDGE technology.

Many operators have already found out that the upgrade of their current GSM/GPRS network to EDGE will form an important basis for their future business.

EDGE (Enhanced Data rates for Global Evolution) is also an "add-on" to the GSM network... it allows speeds around 384-450kbps... not many network providers have support for EDGE, probably since there aren't many phones on the market with support for EDGE.

EDGE (Enhanced Data Rates for Global Evolution) is a 3G radio technology standardized by ITU and 3GPP, built on the existing GSM/GPRS network with minor additions relating to the air interface.

EDGE capability can be easily upgraded to existing GSM/GPRS networks using appropriate software. GPRS on average triples the current GPRS data rates and the capacity of each hardware and frequency channel, enabling lower usage cost for existing end-user services, as well as the new advanced services delivery over GSM bands, such as video streaming.

EDGE enables advanced mobile services to all end-user segments, creating revenue generation over a wide customer base. Due to its high data rates, EDGE has been adopted as part of ITU's (International Telecommunication Union) family of 3G technologies. Currently, EDGE is standardized by the same 3GPP standardization body as the other 3G technology, WCDMA, harmonizing the development of both EDGE and WCDMA, and bringing the service delivery capabilities of 3G to EDGE as well. With an average of triple the data rates with EDGE, Nokia customers in Europe, Asia and Americas have already confirmed the promise of the GSM industry.

All major operators and equipment vendors support GSM/EDGE standardization. All major GSM manufacturers have publicly confirmed that they will employ EDGE technology. Several terminal vendors, including Nokia, are also scheduled to bring dual mode GSM/EDGE terminals to the market starting in 2002 and multi-mode GSM/EDGE/WCDMA terminals to market sometime during 2003-2004. By 2004, virtually all new Nokia GPRS phones will have EDGE.

Forget about 3G , 4G is just around the corner according to The Economist.
Also, it the SE T610 HSCSD compatible, and does orange support it ?
