Was the i830's gsm/cdma combination a once in a lifetime thing or will there continue to be such devices? I am contemplating switching to gsm so I can have coverage in Europe. I (possibly foolishly) think that if I get a 3G quad-band phone, I should have high speed access and world usability.
Why does everyone seem to be so sure that the quad-band flip phone which was released in China is the i770? While there are certain physical similarities between the devices, the China phone does not have a true-type keypad like the i770 (based upon the FCC photos) and AFAIK there has been no confirmation whatsoever that the China phone has Windows Mobile OS. Nor has there been any reliable confirmation that Samsung is even considering a CDMA-verision of the i770 device listed on the FCC six months ago.
There are at least two parts to the answer to your question, colordiva.
1) GSM vs. CDMA: GSM's highest level of broadband is known as HSDPA, and it's comparable to CDMA's current "fat pipe" offering, which is EvDO Rev 0. These services permit data speeds of say, 400-700kbps down and 50kbps up. (As always, "YMMV.")
In the US, Cingular's rolling out HSDPA now, but it's not available in nearly as many markets as Sprint's and VZW's EvDO.
T-Mo, also GSM, hasn't even started to deploy a high-speed network here, so it's a year or more behind Cingular. As such, T-Mo is not a good choice for packet data-intensive wireless service.
CDMA's next-gen broadband system, known as EvDO Rev A, is now starting to come online (Sprint's officially underway in a handful of markets, VZW will presumably start early in '07). It's a bit faster down and up, greatly lessens lag ("low latency"), and alows simultaneous voice and data.
Presently, no phones or PPCs support Rev A, but they'll appear in '07. Some PC cards are now available, however.
2) Devices: Theoretically, feature-set parity can exist between GSM and CDMA devices, especially at the top end, but it often doesn't. While virtually all current PPCs for CDMA support EvDO Rev 0, few GSM PPCs can handle HSDPA. The Samsung BlackJack and HTC (Hermes) 8525 are two Cingular GSM units that at least get this right.
Of course, other device-architecture, form-factor, and feature-set issues need critical evaluation as well, but this is always required.
The other consideration for GSM is frequency support. Quadband is best (850/1900Mhz US, 900/1800MHz EU, plus 2100MHz for EU broadband, where available). Incidentally, most of Europe's GSM systems still rely on a less speedy broadband implementation known as UMTS, but it's adequate.
For those with too much time on their hands, here's the link to the FCC's type acceptance submission search engine.
All that need be entered to look for a particular device is its model number, which goes in the box labeled "Product Description." Nothing else need be entered.
For example, one can search for SGH-i760, SCH-i760, or SCH-i730.
If the i760 ever comes up, it's real--figure we'll see it in 60-90 days.
So search early and often, and be sure to wake up Cap'n Railing when our ship comes in!
Meanwhile, some of us had better get back to work, lol...
BAM, thanks for the primer. I always feel inadequate here with the tech folks, but I do the due dilegence and read up on the stuff as best I can. This forum has been invaluable to me and I thank all of you whose knowledge I have been able to harvest.
I will wait out the rumors and see what gets offered first quarter 2007, but I am leaning toward the Treo 750. The only reason I am even considering the GSM switch is that twice a year I go to Europe and I hate my device not to work. (Apparantly I'm an addict.) I live in Seattle, so Cingular's 3G has me covered here, and a quad band device would cover me abroad.
I am amused to find myself in this place, though. I had an early edition Treo on Cingular years ago (when handspring was really the only one in the smartphone business) and it worked better in Rome and Amsterdam than it worked in my own back yard. Swore I'd never go back to Cingular. Ah, don't you hate having to eat crow?
The ideal situation for me would be for one of Verizon's Q1 or Q2 2007 offerings to have GSM world coverage. Cake & eat it too! Can't bear to get a i830, cause I want a "new toy," not the old stuff.
I guess my question to those who know far more than I is this: What do I give up if I switch from CDMA EVDO to GSM 3G?
This press release does not say there will be a cdma version, but it does seem to indicate that verizon will carry the phone. I can't see them carrying a GSM only phone.

Thats a pretty good find there buddy. As i keep reading this thread and more things start pointing to verizon, i get more and more excited!
As excited as i am to see how this 760 thing unravels, is any one else getting excited about the SGH-P9000 that Samsung has built? I have been readin up on it and it is a pretty impressice device. Wi-max and cdma evdo! I dont know, maybe its just me....
jason - the one flaw I see in this device is that when folded, the screen is covered. When it rings, I assume you would have to open the cover the see who's calling or answer the call. I think it then becomes the world's largest flip phone! I would be more interested in the Sony Vaio UX or the OQO with phone capabilities (a girl can dream!) because they have the screen visible.

I absolutely agree with you which is why, when the time comes and they release this (who know if and when that will be) i will be looking for bt software for talking caller id! that would make me a happy fella. Yea you cant just pop it open to look a the screen but it would be nice to be able to at least hear the caller announced through a headset. Im sure there will be alot of work arounds for these devices and there flaws as they start developing and refining the technology. Smartphones where not perfect when they came out, and now we have beasts like the i730! I just can't help but get excited about the next generation of convergence devices!
wait a minute... maybe i am confused, but i thought the i760 was an evolution of the i730 slider chassis and the i770 was the flip-style phone...
That's the problem with any thread talking about a new device, many people post information about OTHER devices. That post above was talking about yet another device mentioned higher up...

What caught my eye was EvDO visible in the second pic. Verizon seems to adore the Chocolate concept for some reason so this might not be so far fetched but WiMaX?????. Anyway, I tend to shy away from the somewhat flimsy response the devises have with the "heat sensitive touch" . On the other hand I would love a smaller/thinner device...it just seems so overdue. Again, it has to pack a similar hardware punch to the i730 or better or I'm not interested.
The phone is already filthy on it's first day of being shown, and the number keys look pretty flimsy. (Pretty sure I could flick one off with my fingernail and then where would I be with no number 7? ) I touched the chocolate and couldn't stand it. Now that I hear it is heat sensitive that may be why. I use the edge of my fingernails for buttons and screen navigation, not the pads of my fingers.
I am begining to dislike the sound of my own whining. Sorry.
