@Lanbrown - Like I said to sworthy, I know about Motorola's Bluetooth phones. I'm asking not why Motorola has no Bluetooth support (they do; vide V600, V710) but rather why iSync cannot use Bluetooth to put my Address Book onto my (future) V710.
If anyone has any technical documentation about the reasoning behind this (that is, I don't want to hear about the Apple/Motorola iTunes partnership), then please refer me to it. I want to know why Motorola has built Bluetooth into their phones only to leave it unsupported, or, if this is not the case, why Apple cannot make iSync work with Motorola's hardware.
EDIT: I see your link, Lanbrown. I'll check it out.
sigamy said:Very few Verizon phones on the supported list. No LG, Samsung or Audiovox. I wish Verizon offered some cool phones!
third_floor said:See, the US wireless providers don't really have standards (nor do they want them.) You Europeans and Asians just get a network, and it works. Over here we have gajillions of bands and networks and no 3G yet and blah blah blah.
I think I'm getting this Motorola V710, and the USB cable, but I really wish Apple would just go ahead and start supporting Bluetooth in general.
By the way, thanks, fflipper, that clears up a lot.
jettredmont said:Both. First, there are, if I remember correctly, four separate technologies at work here in the US. There are some phones which only support one of the technologies, but most are dual-, tri-, or even quad-mode phones. For instance, Sprint's network is PCS; AT&T's is CDMA; etc. I think someone over here's using GSM (what the rest of the world uses), but the coverage isn't good in general. In addition, yes, phone companies brand their phones when you buy them via software so that even if the network is the same (Verizon and AT&T, for instance, I believe both use CDMA) you can't go to a different provider with the same phone. I'm not sure if this is reversable or not; generally after the just-short-of-lifetime contract expires on a phone it's so obsolete you're better off getting a new one anyways.
I think it's a pretty well understood fact that cellular is a mess here in the US. We're a good decade behind the rest of the world technology-wise, and the gap is only growing.
On the other hand, our tax dollars don't subsidize the cell companies and we have fairly reasonable charges overall ... Cheap buys cheap!

Basically, though, we're divided into CDMA and GSM technologies -- two different technologies, that essentially accomplish the same thing through different means. GSM has been around the longest, while CDMA has made a very decent introduction for itself in the past 4-5 years. (There was TDMA, used by AT&T and I believe Cingular for a while, but they're slowly migrating to a completely GSM system.)
For each technology, there are different bands. For GSM and CDMA we mainly use the 850 Mhz and 1900 Mhz band -- 1900 Mhz is also known as PCS, if I understand it right. (Services like T-Mobile and Sprint are 100% "PCS," meaning they operate completely on the 1900 Mhz band.) Some of America also uses the 900 Mhz band, and I believe the 1800 Mhz band might be used in some instances as well.
For GSM providers, there's mainly Cingular and T-Mobile; AT&T was a player, but Cingular just bought them out. For CDMA, you've got Verizon and Sprint, basically.
The problem with most GSM providers, though, and all CDMA providers is that you're basically pressured to use their phones.
If you're using a GSM provider, you're lucky enough because GSM phones use SIM chips; you can go out and buy an unlocked GSM phone without a chip, if you wish, take it to the provider you want, and they can pop in one of their chips. They're a bit more expensive to buy third-party and unlocked, but you can take them with you to any GSM provider, and you'll always have just one phone, even if you switch providers several times. It's as simple as popping in another chip. I just bought an unlocked SE K700i from eBay, for example, and will likely be taking it to Cingular.
CDMA users are out of luck -- you have to buy a phone specifically from that provider, because of the technologies involved. Their phones are dependent on the provider, and to my knowledge there are no "unlocked" CDMA phones. So basically, if you want to switch from Sprint to Verizon, you'll have to buy another phone as well. If you walk into a Cingular or T-Mobile store, though, too, and bought a phone -- the phone will actually be locked to that service as well. GSM providers aren't in the habit of playing any more friendly with each other than CDMA providers: but the difference is, with GSM you can buy an unlocked phone, and providers will (though ocassionally grudgingly) pop in their chip.
Regardless of technology, all providers like to offer "cheap" prices and special deals on phones because of two reasons: 1) they get you to sign up for 1- or 2-year contracts, essentially signing your life away, and 2) the phone is locked to their service. If you're unhappy with them, that's tough; you're stuck with them because you spent $200 on an otherwise useless phone.
So the end result is kind of a mixed bag; you can buy awesome phones to use here in the U.S., but you're stuck to using a GSM provider. That may not be a problem, depending on your geographic location (it's not for me), but for some people, CDMA is the only reliable technology in their area.
And so ends my long-winded and probably unnecessary explanation.My ultimate advice: if you like to have the coolest, up-to-date phones, buy an unlocked GSM phone off of eBay and take it to a GSM provider. If the GSM network in your area is spotty, just wait a bit, as CDMA phones are slowly catching up -- the Motorola V710, for instance.

talkatron2 said:The detailed discussion by Baron58 is an improvement over the comments by GeorgeTheMonkey, but still has a lot of errors. In particular, the post is filled with pro-GSM bias.
AMPS is indeed the old analog standard from the 1980s. It runs at 800 MHz and is the only standard available in many rural areas today. New digital networks run at either 800 MHz (supplementing AMPS coverage, which is still there) or at new 1900 MHz spectrum.
Verizon has AMPS and CDMA networks, at both 800 MHz and 1900 MHz. Sprint has only 1900 MHz CDMA coverage, but many roaming agreements with 800 MHz CDMA and AMPS networks. Almost all current Sprint phones and many Verizon phones are tri-mode and can work at AMPS and CDMA at 800 MHz and CDMA at 1900 MHz. There are also regional (example: Alltel) and rural carriers operating CDMA/AMPS networks.
The advantage of a tri-mode CDMA phone is you can make a call from almost anywhere in the US. National carriers such as Sprint and Verizon were also leaders in rolling out higher-speed data, which the GSM carriers are only now catching up to. The fact that you cannot import an unlocked phone from Europe is true, but only relevant for the small number of US customers who don't take advantage of carrier subsidies.
One national GSM carrier (T-Mobile USA) started only in the mid-90s and has only 1900 MHz coverage. T-Mobile has the worst coverage of any GSM or CDMA carrier. Two other national carriers, Cingular and AT&T Wireless (which are going to merge next year), started as AMPS carriers, then supplemented that with a digital standard called TDMA, and have now basically completed on overlay of GSM/GPRS at both 800 and 1900 MHz. They have subsequently increased the speed of GPRS data with EDGE, although, unlike the CDMA carriers, they have been slow to roll out higher-speed handsets to take advantage of EDGE. T-Mobile is MIA on high-speed data of any sort (other than WiFi at Starbucks and Borders).
Another problem is the air interface of GSM is incompatible with TDMA and AMPS, so unless you buy a rare GAIT hybrid phone, GSM phones cannot make calls on legacy systems. Many customers, including those on AT&T and Cingular, still use these systems. I got my mom a brand new Nokia TDMA/AMPS phone on AT&T in June!
GSM is the standard you should use if you plan to import phones from Europe. If you use T-Mobile, you can use a European tri-band phone. Cingular and AT&T really need US-centric phones that have both 800 and 1900 MHz support. Also, if you plan to roam in Europe, T-Mobile has the best rates.
However, Verizon Wireless has consistently been rated #1 in coverage, nework reliability, and customer satisfaction. It is the only company publicly executing a coherent plan for near-nationwide broadband-level data access. Sprint has wonderful coverage if you buy its $5 roaming plan and has great and inexpensive higher-speed data.
The national CDMA carriers Sprint and Verizon are the leaders in voice coverage, data coverage and data services. There are many reasons to use other carriers, but GSM is not some superior technology that Americans need to adopt.
When I first run iSync 1.5 my T610 icon changed to a T630 (white). But when i quit iSync and relaunched it, it was back to the red one again!kgarner said:Another picky question. Did they change the icon for the T610? I hate the red one that they use. Any T610 users know about this?
Lanbrown said:What are you talking about? There are five technologies here. The first and oldest is analog, which the FCC will allow the cellular companies to stop selling come January 2005. The remaining technologies are all digital, TDMA, CDMA, GSM and iDen. Most of the companies that offer TDMA are switching their users to GSM, so TDMA is dead. That leaves GSM, CDMA and iDen. Cingular, AT&T Wireless and T-Mobile all use GSM, AT&T Wireless and Cingular also have their TDMA networks. T-Mobile is all GSM. On the CDMA side you have Verizon Wireless and Sprint. On the iDen front, you have Nextel. Nextel will be switching technologies in the near future. So when you say the US wireless operators don't follow standards, that is far from the truth. As for the bands, you basically have two. You have the original band (cellular) which is on the 824-849 and 869-894 MHz range. Then you have the PCS bands, which is in the 1850-1990 MHz range. As for no 3D services, you are mistaken; it is available in select cities.
Apple does support BT, it's Motorola that has decided not to use a standard profile.

Lanbrown said:I agree with most, but you come across as pro-CDMA. I know plenty of people that are unhappy with Verizon.
Lanbrown said:You also negated to mention what can happen January 2005. AMPS is no longer a requirement by the FCC. Cingular can turn their AMPS system off and reallocate the spectrum for GSM.
third_floor said:To me, five technologies / bands is four too many. That's where my "bajillions" comment came in. I was exaggerating. Slightly.
As for 3G, the first EDGE phone (from AT&T) only came out a few weeks ago. I couldn't care less if the EDGE infrastructure is in place; if no phones support it, it's useless.
When I said the US doesn't follow standards, I meant it. The rest of the world is doing fine on a GSM (with GPRS and EDGE), while we have to choose between spotty GSM coverage or older CDMA tech with better coverage. Granted, WCDMA is coming (hasn't Japan had that for a few years?), but that doesn't change the fact that the US is severely lacking in wireless communications.
All of this is moot though, because I want a V710 and I want to sync it with iSync.
People can go on all day about this tech and that, and who is biased towards what tech and blabbity blah, but in the end, what matters is what works. CDMA works where I live and where I go to school. My father's GSM phone doesn't have a signal at my house, or on VT's campus.
So now I have a question. How hard is it to get these Bluetooth profiles onto the phone? Is there some sort of hack, or am I barking up the wrong tree? If so, how hard could it possibly be to add support for the existing profiles in iSync? Methinks there is more than just technology barriers here. Corporate red tape really seems to slow down the advancement of technology that works.
For those of you who don't know what UMTS is (it's a rarely used acronym, at least around here), see this article: http://www.umts-forum.org/servlet/dycon/ztumts/umts/Live/en/umts/What+is+UMTS_indexLanbrown said:And there are places that CDMA doesn't have any coverage. W-CDMA is UMTS, which is available in select cities. EDGE is 2.75G and GPRS is 2.5G.
The profiles are built-in and you cannot add them.
displaced said:Thanks everyone for the responses! (although I can't pretend to have grokked them all).
I was aware of the differences between CDMA and GSM as technologies, but was curious about the practicalities of the differences. From what I've heard, CDMA's primary advantage (from a network's POV) is greater range per mast versus GSM. Given the different population densities between the US and Europe, this has got to be a major consideration.
But GSM's modularity is a clear winner for the consumer. Effectively, you're leasing the SIM from the network, and the phone's yours. Of course, in order to get a subsidised phone, you have to promise to lease that SIM for the length of a contract (usually 1 year). But that leads to some very nice deals. For example, I've been happy with my network (Orange) for 5 years, and get to upgrade to the latest and greatest phones for a bargain upgrade price (usually ~£50) each year. The old phone's then free to do with as I wish. Orange send me a free Pay As You Go SIM card for the spare phone, but there's nothing to stop me signing up with another network (either PAYG or contract) with the old phone. The freedom to take your phone to any network, with number portability being around for 5 or so years, means the nets are offering very good value deals on phones and timeplans.
Technically, our networks in the UK operate on two bands. The older networks (O2 - formerly Cellnet and Vodafone) are on one frequency, and the two newer nets (Orange and T-Mobile - formerly one2one) share the other. A few years ago, this used to be a barrier as you had to wait for the phone you wanted to come out in a model capable of using your network's band. However, every phone for the past few years has been at least dual-band (covering all of Europe), and most are now tri-band for use with US GSM.
Anyway... sorry for dragging things OT!
iSync 1.5's still working fine with my T610, .Mac and iPod.
Lanbrown said:It has nothing to do with Apple, but Motorola and their lack of supporting various BT profiles. Look here to see the various profiles:
https://www.bluetooth.org/spec/
What profiles a company decides to support when they implement BT is up to them.
So how is this the fault of Apple that Motorola made that decision?
digitalbiker said:My question is to Lan Brown. How do you know what profiles motorola is or isn't supporting?
The Motorola V600 phone syncs via bluetooth with WindowsXP and various software programs. Also OSX recognizes the V600 phone and you can send data via Vcard format, mp3 ringtones, etc.
Obviously there must be some reason why Apple isn't supporting ISync through Bluetooth when they do support via the USB cable. But to assume that it is all Moto's fault when other OS's and part of OSX supports the phone sounds a lot like an anti-Motorola bias.
Lanbrown said:Because there are a lot of profiles in Bluetooth. Not every device supports all of them. Those profiles may or may not be used over wire connections. Different profiles are used for different things. You don't use the headset profile to send a file to the phone. The profiles are made for a particular task and define how the device handles what it receives. Just because you can sync using a different application doesn't mean anything. One could create a proprietary profile; this would prevent interoperability. Nokia was known for this, you have to use their software to sync. Nokia is now going to SyncML, which will allow the phones to be synced over a multitude of connections and be software independent. Motorola has used the same program for syncing for quite sometime, which dates back to the late 90's.
JFreak said:bluetooth was developed by ERICSSON and that's the #1 reason it took nokia so long to support that technology. granted, ericsson is not today known of its phones anymore and they are sold under sony-ericsson brand, so you're half right...
