I haven't found any answers so I've decided to "ask the audience".
To my understanding the Rogers Canada network uses 850/1900 for it's 3G primarily 850. Is this true?
I haven't found a mention of a North American release date for the GSM Diamond. Anyone know the date? I don't expect it till around Christmas.
I'm looking at an Australian Diamond that uses the 850/2100 bands for 3G. Will the support of the 850 band be enough to function on the Rogers network or does the phone have to support both bands for 3G to function on the network?
only gsm 850 works on my diamond. i think its 1900 for 3g
I have an European Diamond which works on the rogers network but I get GSM/EDGE but to my horror no 3G
Looking around only on a few sites can I find any mention of what works and what doesn't the closest information I could find is from this link:

NextG phones are 850/2100 capable, so you'll be right on most 3G networks...

and they go back and forth so I'm not sure what to believe and I don't think I want to buy another Diamond just to find it won't work either.
http://www.geekzone.co.nz/Jama/585 has some interesting comments as well but I'm not sure what to believe.
Can anyone confirm or deny and of this?
The question is will a Australian phone with the 850/2100 3G radio function on the Roger network?

I have the Australian version (850/2100 MHz) and it supports the Telstra 3G Network. Can't see why it wouldn't work on other 850/2100 MHz 3G network.
To my understanding the Canadian Rogers network is a 850/1900 network.
Does the phone need to support both bands or will one suffice?
Rogers Diamond
I had an EU/Asia Diam and I never manage to get 3G connection. Sold the phone and bought a Rogers branded diam and by default I see 3G connection all the time on the top network status. But now I'm thinking of going back to an EU/Asia version unless I can flash my Rogers branded diam with a better ROM.
So good news for all Diamond euro owners in LA (and other places of course)...the tmobile network supports the 2100mhz band for 3G so no need for a US version!!
http://support.t-mobile.com/knowbase/root/public/tm23715.htm#7
Sorry if this is old news, but i just realized it =)
this is great if true?
T-Mobile devices use the 1700Mhz/2100Mhz frequency band (for 3G) and I thought Europe 3G devices use 900Mhz/2100Mhz. Could U clarify further...
you said it correct...tmobile does use 1700mhz/2100mhz, and the euro diamond supports 2100mhz which should work since tmobile will be using it...i spoke to a tmobile tier 2 rep, he confirmed it as well...
That can't be right. T-Mobile AWS 3G uses the 1700 MHz band for uplink and 2100 MHz for downlink. I doubt T-Mobile US set up aside any channels in the 2100 MHz band as uplink channels.
It's kind of academic, as I can't get 3G on T-Mobile USA using a Euro Diamond in NYC, where we've had 3G deployed for a few months now. I've never heard of anyone else doing it either. Oddly, there's a "UMTS(1700)" selection in the band settings in the phone control panel, but if I try selecting that, it just jumps back to using T-Mobile's normal PCS band with EDGE for data.
If that tier 2 tech can get you onto AWS 3G with your Diamond, definitely let us all know about it, but don't get your hopes up too high.

AWS?? well the tier 2 tech did say it...i dont know if he was just talking out of his ass or not...but we'll see in the coming weeks...ill try to get tmobile rep on the phone again to ask them how i can get it...or if i can, even though its supported..

As I understand it, if a phone says it supports 2100 it is referring to the UMTS Band 1 used in Europe which is 1920-1980MHz Uplink & 2110-2170Mhz Downlink (see UMTS Frequency Bands - Wikipedia). The 1700AWS Band (UMTS Band 4) uses 1710-1755MHz Uplink and 2110-2155MHz Downlink. So, while they do overlap some they are not identical (A Visual Guide to AWS - PhoneScoop)
So, I don't believe that a phone with 2100 EU support will work with T-Mobile 3G because it doesn't support the 'right' 2100 nor the 1700. Likewise, I don't believe that a phone with 1700 support will work for 2100 EU.
If you want to get technical the "US" Diamond won't work for 3g on T-Mobile either. The 3g band is only for 850/1900. (so i guess we're screwed either way) I'm in Salt Lake City and I don't believe Utah is slated to get 3g until 2009 at this point. I bought the diamond knowing full well that 3g was going to be a slim possibility on this phone. However, a user with a DIAM100 is claming that he's been getting 3g service on T-Mobile in NJ. He said that he'd post screenshots.. I don't know if he's done that or not. I guess all we can do is wait and see.

Do you know who this user is? maybe i can PM him and get some details...i knew i wasn't going to get 3G with the diamond, but after talking to the rep. i kind of want to look into it more since there may be a possibility.

Honestly I'm gonna go ahead and call BS on him for that, I've never heard of anyone getting T-Mobile 3G and I know quite a few people with the Diamond/Raphael on T-Mobile in 3G areas.

I have the USA sold "quad band" euro diamond distributed by htc USA. This is essentially re-flashed euro diamond hardware sold to support american networks, not the 850/1900 newest USA 3G diamond compatable with AT&T. I have looked into this issue and also talked to T-mobile and there seems to be alot of confusion regarding T-mobile's AWS USA 3G network (or maybe they have simply confused me). Here is what I have found out: Assuming they are correct, they are telling me 3G voice for T-mobile usa runs in both the 1700 AND 1900 mhz band, and therefore my euro diamond shoud be supported at 1900mhz for voice 3g support. This 1900mhz is part of the "quad band" voice radio hardware on the euro diamond. Data (AWS 3G for USA) "HSDPA" , which T-mobile has not yet released, runs in the 2100mhz bandwidth, and Data AWS "HSUPA 3g" runs in the 1700mhz bandwidth. Therefore my hardware would not support HSUPA @ 1700mhz, but would support the HSDPA @ 2100mhz. As to the idea that euro bandwidths are different than USA bandwidths, well apparently they are. For example "2100mhz" networks in europe might be actually using 2110mhz-2170mhz, whereas in the USA T-mobile's network may use 2100-2140mhz actual bands. However because these are close and still in the 2100mhz band, there should still be compatability with 2100mhz hardware radios regardless of networks varying the bandwidth slightly.
Of course this may be too optimistic, but it would be very cool if true and I am hoping for the best .

Unfortunately, they've provided you some bad information. Each frequency band/range has a pair of uplink and downlink frequencies - you can't use one without the other - you have to use both. Generally, the uplink and downlink frequencies are relatively close to each other however, the 1700 AWS band has uplink and downlink spread quite a distance apart. Uplink is in the 1700MHz range, downlink is in the 2100MHz range and both have to be used. In the US, 1700 & 2100 is essentially one band.
1900MHz (the PCS band) isn't 3G for T-Mobile (although they technically could put it there at some point.) Right now, 1900MHz for T-Mobile is EDGE voice and data. Most other carriers do have 3G on the 1900MHz band, T-Mobile just doesn't have enough spectrum available in that band.
In short: A phone that supports UMTS 2100 will not work for T-Mobile US 3G. A phone that supports AWS/UMTS 1700 will work for T-Mobile US 3G but not for European 2100 3G. (And 1900MHz PCS will give you traditional EDGE on T-Mobile US.)

You may be out of luck on 3G. To the best of my knowledge, I believe Roger's 3G network runs on the 850 and 1900 MHz bands. However, the G1 runs on T-Mobile's 1700 and 2100 MHz bands. So Edge is the best you'll get (speed-wise).

T-Mobile's rollout of UMTS in the US will focus on the 2100/1700 MHz bands, whereas UMTS coverage in Canada is being provided on the 850 MHz band of the Rogers Wireless network. I think 1900 was added later as well.
My HTC HD is edge (2G only). But I use a lot of WiFi when ever possible.
Should I buy a captivate or a i9000 galaxy s?
It is for the use in the netherlands but I heard the captivate had some more specs..
Thanks in advance!
Galaxy S and captivate are pretty similar.
i9000 has front camera (if you use it), physical back button, better support (more users) and you are more likely to have warranty support in the Netherlands.
i897 IMHO looks better and is heavier (feels more expensive). Also it comes in 16gb (i9000 comes in 8gb/16gb) and has lots of AT&T crapware on it....easy enough to remove...but you have to do it
Take the one you like the looks of better.
I really like the looks of the captivate but I am worried that it's going to have 3g network problems here..
If I would import the phone, would it work perfect with the signal here to?

The issue will be the 900 band will be missing in the Captivate which is where a lot of carriers have 3G in Europe. In the US, it will work fine. i9000x 3G won't work in 850Mhz markets.
Captivate runs on the following data bands:
3G (850/1900/2100 MHz) <-AT&T works fine.
Galaxy i9000x runs on:
2G - GSM 850/900/1800/1900
3G - HSDPA 900/1900/2100 <- Missing 850 for AT&T
Vibrant
3G - HSDPA 1700/2100
If you seriously want a world phone for data, there is only one in the market at the moment that I'm aware of. It's the Sony Xperia X10a. It's a dual mode phone and uses GSM/GPRS/EDGE 850/900/1800/1900 and UMTS/HSPA 800/850/1900/2100.
I'm a complete dummy in this subject so here comes the stupid questions..
What would happen if I tried using it in my country?
I'm using a omnia 2 now with:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1900 / 2100
So if I tried using the captivate, would my 3g be gone?
EDIT:
I was looking through the specs at the AT&T site and it said:
GSM/GPRS 850/900/1800/1900 MHz
3G UMTS/HSDPA (850/900/1900/2100 MHz)
So according to these specs it says that it also has a 900mhz frequention.
EDIT2: Vodafone in my area (my carrier) uses 2100 as 3g band and gsm 900/1800.
I foung this info using gsmworld
can someone please explain it to me?
Ik need to choose before friday!
Hi guys,
I've had a look around and can't really find much info on bad ESN's. Most of the questions are resolved with a -"find a carrier who will reflash your phone". The phone I'm looking at is from someone who didn't pay their phone bill. If I import this phone over to Australia - what will a bad ESN do? I'm planning to buy a pre paid SIM card over here, and I'd like to put a basic Gingerbread rom on it.
I can see that a bad ESN means you wouldn't be able to use the phone on the network it was sold on, but if you unlock the phone doesn't that mean you can put on whatever carrier you'd like?
Are there any issues with doing this?
The next part of my question is about the Vibrant. From the info I've found this...
Will My SGH-t959 (Vibrant) Phone Work In Other Countries And How Do I Unlock It?
The SGH-t959 is a quad band dual mode handset. It supports GSM frequencies of 850, 900, 1800, & 1900. It supports UMTS 1700, 1900, and 2100 frequencies. There is a possibility the phone may be used with a wireless operator outside the United States however this is not guranteed. The phone has been optimized to work on the intended carrier it was designed for.

From what wikipedia says on Vodafone (in Oz,)
The GSM mobile service on 900 MHz and 1800 MHz covers 94.52% of the country. The 3G 2100 MHz UMTS network is available in metro areas of major cities and some larger regional centres covering 80% of the population. Expansion of the 3G UMTS network using 900 MHz to equal or surpass the GSM coverage is due to be completed by 31 August 2009 [1] [2].

I can't guarantee it but technically according to the site below, it should work:
