We'll see how it goes. I didn't know about the GSM limitation (not having analog as well) until I started researching this. I would think that uptake of the Treo, etc., in the US would be much higher if it also had analog support. Thanks for the offer on the hands-free. I thought I found one at BestBuy - it claimed it was for Qualcomm and looked similar, but the connection was different. It was for a different model Qualcomm phone. (I think you're right that it's the same as the Sony though.) I think my phone's a lost cause. I haven't been able to charge it since I dropped it in a toilet a few weeks ago. It was only there briefly, and I quickly dried it off and had it in front of a fan for 24 hours before turning it on. It comes on and works, but the charger doesn't do anything to the battery level. Since it was only $50 (refurbished) from Sprint, it's no great loss. Not worth buying another battery for.... If I decide I really need a combo PDA/phone, I might go with one of the clip-on Motorola [link\|http://www.cellularaccessory.com/motstarclipo.html\|organizer thingies ] for the StarTAC for $25-30. But I'll probably stick with the Handspring for a few more years, so end up using both the phone and the Visor. Thanks again! Cheers, Scott.

Basically, the US and Japan are the only major countries that didn't embrace GSM when everyone else did with the result that everywhere else is either exclusively or predominantly GSM (or nothing at all). The US's stubborn-ness meant that one of the US systems collides with one of the standard GSM bands, so another was eventually created. HandSpring decided it wasn't worth locking themselves into the US market with an Analog phone, which explains why they went GSM. They also investigates a dual-mode phone but that would have delayed the product, made it much more expensive and considerably bigger. So they stuck with GSM. Wade.

It's interesting to note that two of Sprint's biggest suppliers are Korean (Samsung and LG). AMPS is the original analog cell phone system; IIRC its technology dates back to the 1970's (and Motorola). Since the US was ahead in cell phones, we built up a large analog cell phone system, which still has better coverage than any of the digital systems (the US is a big country, and the greater range of analog (25 mi IIRC) versus most digital (5 mi for CDMA, GSM) helps. I can easily drive places where there is no digital signal -- and I doubt it'd be any different if the US had moved to GSM, since they're isolated spots) Of course, when the US moved to digital, the cell phone companies moved to 4 different systems: CDMA (Sprint, Verizon), GSM-TDMA (Voicestream, PacBell), a different TDMA (AT&T), and yet another TDMA system with 'radio' features (Nextel). Four systems plus analog is a mess. Given the initially spotty digital coverage (it takes several years to build up a network in the US) and widespread availability of analog systems, it made sense to support dual mode (digital/analog) phones, at least for Sprint and Verizon. As the carriers move to 2.5G systems, the US is consolidating on either cdma2000 or GSM/GPRS. Yes, there are advantages to one system, as in Europe, but it still isn't perfect (being able to use one of three crappy signals isn't any better than being able to use one crappy signal -- I've had personal experience with this). And, if the carriers worked on cooperating (e.g. SMS across GSM/CDMA) many of the disadvantages of multiple systems go away. I suspect there's more to the frequency allocation issue; different parts of the world developed their own frequency allocation. IIRC, Bluetooth uses frequencies that France uses for military use. GSM phones can use one of three different frequncies, so it isn't just the US that's different. Now I still think Handspring made a good decision to start with GSM, although they will be coming out with CDMA versions this summer. Tony
Post #38,583 by static 5/14/02 8:05:27 AM Reply	Interesting perspective. I'll admit what I posted was from memory. That includes remembering that the US seemed strongly inclined to disdain GSM as a system and that the third GSM band was added partly because the second clashed with other US cell-phone tech. But both facts might well be distorted. OTOH, I do recall the multi-system craziness in the US was widely regarded as the height of lunacy. :-) Analog in AU was AMPS. If it isn't switched off yet, then it nearly is because GSM licenses were issued with a guarantee that the AMPS system would be switched off on Jan 1, 2001 (there was a legal challenge to the switch off).

I might be interested in using it if I knew more than one person who uses SMS. What makes it interesting is that they list the technology and frequency (in hundreds of MHz), although it's not complete (e.g. they miss the biggest US carrier, Verizon). Also, I should note I'm really not a cellular geek; OTOH, I do have an uncle who's spent over thirty years in radio and cell phones. Tony

Post #38,603 by dmarker2 5/14/02 9:33:58 AM Reply	Re: Where is CDMA in China ? When ever I go there it is GSM - Motorola sell GSM phones there as do most other suppliers. China is regarded as the fastest growing and potentially biggest world market and it is GSM not CDMA that dominates. Cheers Doug
Post #38,626 by Another Scott 5/14/02 11:33:27 AM Reply	Story from TheInq on China's 2.5G system. [link\|http://www.theinquirer.net/14050208.htm\|Here]. The other big Chinese firm, China Unicom, introduced CDMA (code division multiple access) services earlier this year but although China Mobile is plumping for GPRS, the technology is not quite ripe, with high speed Internet connections still something of a pipe dream. Cheers, Scott.
Post #39,103 by dmarker2 5/17/02 8:06:47 PM Reply	Re: As I understand it ... CDMA phones are incompatible with GSM & don't use removable SIMs - that is the single biggest thing against CDMA phones as this part of the world (apart from Japan) have become used to & mostly want SIM based phones. CDMA services are vexing to transfer from phone to phone (a common practice here). Cheers Doug
Post #39,237 by tonytib 5/19/02 11:03:06 PM Reply	Life isn't perfect in SIM land, either First off, SIM cards have the predictable security problems (how come good security is always an afterthought?). One very interesting approach (to clone SIM cards) is to monitor external, physical stuff like power consumed and radiation levels. IIRC I saw that article on The Reg. Second, it's not always possible to switch carriers, since if you buy a phone from a carrier (often cheaper since the carrier subsidizes the price) they can "lock" the phone to reject other SIM cards. To give two examples, I could not use an Italian SIM card in my German GSM phone, and a friend who took his Cingular phone to Hawaii had to call and complain a lot to get the master unlock code so he could use a non-Cingular GSM card. It's also interesting to note that cell phone theft seems to be a big problem in Britain (or at least visible problem), based on coverage in The Reg, whereas it doesn't seem be a big problem here. With all of that said, there's a lot be said for transparent roaming (phone picks up the strongest signal for whatever carrier) and easy change of carriers -- it's definitely a lot harder to change in the US. And, despite the problems with GSM in reality, it's much, much closer these ideals than CDMA or mixed systems (like in the Americas). BTW Doug, have you been seeing the hype for public access 802.11? I've been seeing a lot of articles about it here; apparently some people think it may cause a lot of problems for 3-G cell phones. Tony
Post #39,559 by dmarker2 5/22/02 8:44:30 PM Reply	Re: I agree re 802 impacting 3G same news here. I have a 802.11b CF card that I can run in my Sharp Zaurus (and using that clumsy jacket, in my iPAQ as well). Here there is activity setting up 802.11b in coffee shops & building foyers & all I need do is turn on, access my email account (these services are being set up my my ISP (also my employer)). The belief is that 802.11b & the faster 802.11a (I think it is a) will negate a lot of the appeal of 3G. But if the average consumer thinks it is fantastic to use their phone to send pics or video clips to each other (here we have the Sony/Ericsson T68i phone that has such a camera that attaches to it), then I guess there could be heavy demand vs 802.11x which may better suit business people. The T68i works on GPRS (2.5G) - I have the T68 (prior model) got it for its bluetooth & GPRS connections. Cheers Doug PS at a recent demo at MS an MS guy showed us a PDA/Phone that was same size as a iPAQ - made by the same mfg that builds iPAQ for Compaq, runs Win2002. A bit heavier than an iPAQ but very sleek & slick looking. Supposed to be released at end of this month - sports a GSM module & dual band.
