I know that UMTS can carry data (just as GSM did in the old days of CSD).

HSDPA is an extension of UMTS in the same way that GPRS/EDGE is an extension of GSM.

I can see when im on EDGE GSM or GPRS.
I just hope that the Data is released by June. I think that the 3G should be released by June because thats when the xperia is set to come out and the HTC Touch Dual should be on T-Mo by then because supposedly its hitting shelves in the US in may.
Hrry up T-Mo i want HSDPA already

First of all, GSM was able to do DATA even before GPRS but it is similar to dial-up where you have to dial a number. GPRS is the packet data and somewhat "always on" thingy....

Also, UMTS is NOT ONLY 3G for voice because when I first used 3G back in Singapore (in 2005) they DID NOT have HSDPA yet and we relied on UMTS for 3G data, voice, and video calls.

UMTS speed I believe only up to 384 kbps whereas HSDPA can achieve much much more.

UMTS is "3G for voice", and is what AT&T uses. HSDPA is the communications protocol that is used on UMTS networks for data.

GSM->UMTS
GPRS->HSDPA

CDMA operators in the USA use EVDO for data ONLY, and still rely on pre-3G protocols for voice.

]]> <![CDATA[On TMO Doing 3G Voice Only...]]> Data speeds have nothing whatsoever to do with voice...there is, as bfk says, no such thing as 3G voice.

]]> <![CDATA[On TMO Doing 3G Voice Only...]]> @bfk: Um, I use 3G for voice everyday on my AT&T wireless phone. Their is a noticable difference between calls on my phone on GPRS and UMTS.

]]> <![CDATA[On TMO Doing 3G Voice Only...]]> Yeah, I was wondering what the point of 3g for voice would be. seems like a lot of bandwidth for it.

capitalass

]]> <![CDATA[On TMO Doing 3G Voice Only...]]> um, thats not even close to true. in fact, cdma carriers exclusively use 1x for voice, there is no such thing as 3g for voice.

]]> <![CDATA[On TMO Doing 3G Voice Only...]]> Dang...but...well....

Will I be less likely to lose a signal on the road then?
