Can the DHD really work in the US?

According to a couple of people here the DHD can work for tmo ON 3G in the states if you unlock the sim apparently how much of this is true?

Dhd works on gsm. Any septic supplier on gsm will provide service. Just like any other gsm phone. I sent ny dhd to canada and it worked great with Rogers and telus.

Did 3g work? Or edge?

It never ceases to amaze me how many people ask this question when the information is so easily obtained. In the spirit of you asking a question which has been addressed countless times on XDA forums in general, I will not provide you with an answer but the tools to find them.
Go here:

...and match with what you find here:

Hint: btw "UMTS" means 3g freq.

Ya. It worked in Mexico, L.A., and Vancouver. I didn't use it much ad T-Mobile U.K. charges £7.50 per mb downloaded when you're roaming. I used a Mexican sim and a Canadian sim and it all worked. Gsm is normal in Europe. Cmda only seems to be in the states from what I've seen. Sorry sprint hero and evo users, I'de never heard of a phone without a sim abd that's coming from a Canadian across the Atlantic living in London.

canada/usa users opinion plz :-)

ok, i am pretty happy with my x10a but will be travelling to key west florida in about a month. what id like to know is whats the latest android device in the usa with a hard keyboard? ive heard about the droid global but not much. im asking because i am from canada and we are always 6+ months behind cell technology so id like to pickup a new device as good or better than the x10. i do a massive amount of texting which is why im thinking of the hard keyboard option. i am also with rogers canada so i would need advice as to what phones would even be compatible on their network, and obiously be able to sim unlock it.
i look forward to your guys opinion, as im lost on devices outside of canada thanks guys!

The U.S. is 2 years behind. So you are lucky!
You are probably better off getting advice from people in Europe/Asia/Middle East. They get all the good stuff before us is North America.

at&t and T-Mobile are both GSM. You will get EDGE working on both of them but, they use different bands for 3G.

For 3G, at&t and Rogers use the same band, I think 800/850/1900. T-mobile uses a different band, I think 900/1700. Most European/Asian/Middle Eastern countries use 2100. South America and Australia, use a mix of both depending on the operator.

You could go into a AT&T store while you are here, and get a free "GO" phone which is a monthly prepaid thing for your stay. And get a Google Voice number before you leave.
Leave the X10 connected and set it to forward the calls to the Google Voice (I don't know if Rogers would charge you for this or you would need a US google number or not) and link the Google Voice to your temporary Go phone. Depending on how much you were willing to pay, you could get a free flip phone or pay for anything up to a blackberry.
You would need access at least once to a PC after getting the phone to reconfigure Google to transfer the calls and SMS the phone with the texted version of any voice message.
Even Walmart has these too: http://www.walmart.com/ip/AT-T-Nokia-C3-Prepaid-GoPhone-Blue/15140306

the HTC desire Z seems like a viable option!

To be honest rogers had the x10 before att got it. They aren't that far behind the north American curve, but if you want a good phone, get a bell desire z. Then unlock it. The bell one has a front facing camera and it'll work on rogers. Plus it has the hard fold out keyboard.

Trade T-Mobile N1 for AT&T N1?

I bought a used N1 on eBay. I totally wasn't even thinking about the fact that there are different models of the phone for different carriers. Turns out I have the T-Mobile N1, but I have AT&T service currently.
I assume that there is no kind of mod/firmware to get it to use AT&T 3G, and that it's the hardware that limits me to T-Mo? Probably more than some custom firmware or something could fix?
That kind of sucks, if so. I doubt anyone would have an AT&T model, looking for a T-Mo model, eh?
Thanks for any help, if it's even possible..

Have you looked at the seller's return policy?

No returns accepted, as stated on the item page.
I can live with it (in remorse)..
The seller didn't mention what model it was at all, either.
I don't suppose Verizon uses the same bands as T-Mo?

No, they don't. T-Mobile and Verizon use totally different radio technologies.
Go onto the Marketplace forum on XDA, and trade/sell it through there.

Post it for sale locally on craigslist to finance a unit with the AT&T radio.

Also if you have trouble locating the AT&T compatible N1, you may also consider the Telus version of HTC Desire. Largely the same hardware, AT&T bands, but no Euro 2100 band.
Possible bonus: AT&T does not know the IMEI of Telus Androids, and might not force you to a higher cost smart phone data plan.

Thanks for your input, guys.
I'll try first to sell it locally via Craigslist.

I really think that it will be much more difficult
since they discontinued the Nexus One, and provided it through the developers only,
it has always been the T-Mobile version which is quite disappointing....
the AT&T version seem to just disappear from manufacturing all together
point I am trying to make is that it the AT&T version should be much rarer and possibly worth more on the market since there are less quantities of it
it sucks my friend I feel for you...

How is the T-Mobile N1 different from AT&T model?

Different radio frequencies and limited availability. Otherwise identical.

If you Unlock the S off on the nexus one Tmobile. You can use a At&t sm card with out a problem. I UnloCked the S off ON the mytouch 4g AND IT works on At&t s network. HMMMM. Wondering if it works.

Yes, it will function on the network. The issue is that the radio hardware is built for specific frequencies, which differ between the T-Mobile and AT&T models.
You can use one phone on the other's network just fine as a phone, but you will be limited to 2G data speeds, as AT&T uses 850/1900MHz for their 3G data and T-Mobile uses 900 1700/2100MHz.

Umm, nobody uses 900 MHz for cellular in North America... that spectrum is not allocated for that purpose here.

You're right, my apologies. The fact of the matter (that the hardware is incompatible between the AT&T and T-Mobile networks) remains intact though.
Correct 3G data frequency information, as best I can make it out:
AT&T uses 850MHz and 1900MHz.
T-Mobile uses 1700MHz and 2100MHz.
900MHz and 2100MHz are used primarily in Europe; a phone made for European markets will have a better chance of being fully compatible with T-Mobile's network in the states based on sharing the 2100MHz band.

Closer but still not quite
Read up on the AWS band. European phones will not get T-Mobile 3G at all without 1700.
But in the specific case of the Nexus One, models sold in Europe do have AWS.

I just got the mytouch 4g and i wanted to sell my nexus one. But i wanted to double check and see if i can sell it to someone on the at&t network. I currently have tmobile. I thought the S-Off was to completely unlock the phone. So u can switch between carriers. Didnt know the frequency would be different. thank guyz. Damn u HTC.

Did you check to make sure what GSM frequencies the carrier uses (sorry not familiar with El Salvador)? This sounds very similar to people trying to use G2's on AT&T / iPhones on T-mobile. Not all GSM carriers use the same frequencies for their service. If voice is working, but 3G data is not, this is very likely the issue. For example, AT&T operates both 2g and 3g on 850/1900, whereas T-mobile operates 2g on 850/1900 and 3G on 1700/2100; hence why voice and Edge can work, but 3G cannot.
Poking around a little, the X10 mini world phone version has an 850/900/1800/1900 for edge and 1900/2100 frequency radio for 3G data connection, although there are AT&T versions with slightly different bands too, which you may have I'm not sure.
The G2 runs on T-mobile in the US and has a 850/900/1800/1900 for edge and 1700/2100 radio for 3G data.
All according to Wikipedia from what I can scrounge up right now.
BTW I feel proud that I did this research lol. Enlightening.

I think tigo is at 850, is there anything I can do at this point?

If Tigo doesn't run 1700/2100 3g, there isn't anything you can do short of selling your G2 and buying a European Desire Z (same as G2) with the proper frequencies assuming you want the same type of phone. Shoulda checked this out lol just cuz it has a SIM slot doesn't mean it "just works" haha. sorry!

I believe that the Canadian/European Desire Z is the world phone edition which carries band support for all GSM bands. It is the USA T-Mobile G2 that carries support for the GSM bands specifically for the US market. Correct me if I am wrong.

There is plenty of cdma coverage in India. Only Eastern Europe has CDMA. However getting to work is no cakewalk and could permabrick your phone (all sorts of QPST nastiness).
Personally, I would just buy a used Captivate on craigslist for $100, then unlock it yourself and use that with a local carrier. It's less messy (phone wise, GSM only requires you to pop in a sim) and really isn't that much of an expense in the grand scheme of things.

As noted, there's lots of CDMA in India. I just used my Epic there last month. But the UK is out of the question as there's no CDMA there in the frequency bands that Sprint uses.

All the other options to try and buy GSM phones are not something I can use, as I am trying to sell my friend my phone, an Epic bought and used in the US, so I can move on to another phone and use that money. The question was whether this phone can be used in India and the UK. Some of you said you have used it in India. Did data and everything work? How did you get it to work?

Either way it's tedious and requires you have an indepth knowledge of QPST.
The legal way requires the Indian Telco to accept your ESN (which they probably won't).
The only other way is either personally knowing someone who works for the telco to add your phone anyway or cloning which is even more tedious and possibly illegal.
With GSM, buy a sim, pop it in, go on with your life.

Yeah but we need ways to sell this phone.
I'm sure op is down fr some qpst time
