After researching for weeks and weeks i recently found that there will be 2 different versions of the phone. one for north america.. the other for the rest of the world... something regarding patents of broadcomm or something... but looks like the USA version will not have VGA video capabilities with 30fps... it will be less at 24fps.
another difference is the network.. 850Mhz vs 900mhz GSM?
anyways....
i am wondering... it will probably be possible once both phones are launched... to buy the USA version... and flash it to the NON usa version's ROM??? and is that advisable.
also how much with 2yr contract you guys thinking it will cost??? im guessing 499-599 for the first couple weeks.
also... are the frequencies :850/1900/2100 MHz: related to HARDWARE of device and independent of ROM? say i flash rom to the europe version... will i still have UTMS 850/1900/2100 MHz or will it be 900/1900/2100 MHz... and im guessing the 900 wont be utilized since ATT doesnt use it.
and if i lose the 850mhz range... for utms by flashing .. if so.. will i really experience signal quality drop?
sry for all the questions.. im not very familiar with these stuff.
ps: but i heard it will be a hardware limitation so even by flashing rom... USA version will not be able to decode h.264 video am I right?
SonyEricsson Website Has 5 Bands

Yes that's very doubtfully in the same version, that's what he's saying. 2 different versions, likely 850/900/1900/mhz UMTS on one, and 900/1700/2100mhz UMTS on the other. As for hardware limitations, almost definitely. I can't imagine having 5 bands of UMTS available in 1 phone, I think it'd have to be bigger. You could flash a new ROM independent of radio, and not mess up the coverage, sure.
As for your questions about 850mhz, here's how it goes.
AT&T, in the US: 850/1900MHZ UMTS, depending on the area it will be 1 or the other.
T-Mo, in the US: 1700/2100MHZ UMTS, both active at the same time, one for upload the other for download.
Europe: 900MHZ (I believe) UMTS
Asia: 2100MHZ (I believe) UMTS
So with AT&T, losing functionality of 1 band will limit your reception in certain parts of the country... But don't flash a new radio and it should be fine.
As for carrier, I don't know if any in the US is going to pick this up and sell it subsidized. If not, you're shelling out all $900+ for this baby with no contract.

I have confirmed the compatiable in the USA with T-Mobile's USA 3g and AT&T's 3g, I have confirmed this with SonyEricsson. The 2 versions are "a" and "i", this may have been the intentions of SonyEricsson in the beginning, but may have change to one worldwide 5 band Xperia X1, this part has not been confirmed. Here is a website that tells you what carriers in the USA the Xperia X1 will not be compatible with at all. http://www.smart-mobile-gadgets.com/welcome/cart.php?target=product&product_id=1236 Also it will tell you all bands and carriers the Xperia X1 will be compatible with in the USA........!
interesting. well i sure hope ATT picks it up so i can do it with a contract and save some cash on the spot
so has it been released officially and confirmed in germany.. and those other countries?
also... with the "usa" version that doesnt do 30fps...
will it play pretty smooth any videos that i put on it? like movies .mp4?
It's supposed to be able to play 720x480 (DVD Quality) movies smoothly so I don't see why it shouldn't.
Time will tell if it can play movies properly. Its a driver issue.
Can the Diamond play normal Xvid files? I doubt it.
This device shouldnt neither unless it has some good drivers and unless the ram acctualy makes the playback more fluid.
i heard its supposed to have some ati graphics card in there for that aspect of things. so im thinking it will do fine... i guess we wait and see reviews..

being compatible and getting 3g is totally different. one version can work on at&t and only receive edge instead of 3g cause it is missing one of the bands....

I don't trust the spec from someone who just want to attract buyers. They don't even have a final production box in their hands. Where they got all that from?
Those specs are wrong and wrong. taken from old sources. The first line is true, but you go down the list and it is only inaccuracies, so what you believe?
3G network. How they know?
Size. Inaccuarte
Memory phone book capacity? Are you kidding me?
400 MB internal memory. What? that's not even a binary number.
HSDPA 3.6 Mbps? I know it is 7.2
W.M 6.0? They didn't even got this one
Motion Sensor? ha ha ha ha
Battery standard Li-Ion? What happes with the Li-Po
Would you buy from these guys? How do you know what's coming in their box?
and by motion sensor their relating to accelerometer...and indeed the xperia does NOT come with that.. so screen will not rotate itself as u rotate phone. switching to landscape mode and vice versa will take the flick of a button/option.
Can anyone tell me if there truly was an X1a protoype or if all prototypes were X1is?
x1a is the european version where the X1i is for American users.
must have something to do with fcc rules

Actually that is backwards. The X1a is for American users and the X1i is for European users. There were some hardware changes if i'm not mistaken because of a broadcom part or something like that.
hmk,
isnt the UMTS Frequency different for the american users? i remember people complaing about non working UMTS in the USA cause they bought a EU one.
and i also remembered that FCC aprooved the X1 bout a month or two later
Yes there is a difference in UMTS frequency bands. The X1i has 900/1900/2100 i believe and the X1a has 850/1900 and there is a third one but i can't remember what it is. People who bought the X1i and are in an area in the US where they only have 850 can't get 3G.
Thanks guys for the input but I am looking for information if a Sony X1 prototype could be the X1a or the X1i. I have a friend that has a prototype I could acquire but I am not sure if I want to wait on the X1a when it finally ships or get his prototype. The phone has no distinguishing markings to state it is a X1a or i. It picks up ATT 3g fine here in Atlanta but I beleive we are almost all 1900mhz. Just trying to find out the best way to tell if it is an a or i. Thanks.
I've never heard of an X1a prototype but i can't say its impossible. My X1i says X1i in the device information in the identity tab. I'm not sure if the X1a says "X1a" or something else.

This phone says "Prototype" where the others list X1a or X1i.
does it have the original rom?
Not sure but I could see if he will check. I may not see him for a few days though. I am now assuming it is a X1i as I learned his brother works for SE in Sweden and sent it to him for testing.
i did use the search button, but everytime i click on it i get an error saying Page Cannot Be Displayed so i dont know whats goin on, but i just wnat to know what is the difference between the X1a and X1i and want to know which one of them is better? Please let me know guys, and sorry about the search...i did try
X1i = interesting
X1a = awesome
You didn't search, Google it!
x1i == 3g but not with 850umts band and record at 640_480 30fps
x1a == 3g with 850umts but think it's lacking support for some the umts bands used outside America and can't record 640_480 at 30fps
I picked up an X1i myself due to the 30fps recording.
X1a: UMTS 850/1900/2100 MHz (15fps video recording - lowered due to patent infringements)
X1i: UMTS 900/1900/2100 MHz (30fps video recording)
If you're a a North American using an 850MHz provider (such as AT&T), go the X1a, if you're in Australia, go the X1a (for Telstra/3 customers) and the X1i (for Optus/Vodafone/Virgin/etc customers), if you're in Europe go the X1i.
I'm not sure about Asia though, sorry.
I got the X1a because of Telstra's 3G network using the 850MHz band.
I was wondering if some one could help me please. I read in the above thread to buy the X1a if on telstra/3 but 3 have just released the X1i. Now i was just about to buy an X1a because 3 are launching the mega 3g soon which allows 3g on telstras umts 850 band (of which the x1i doesnt have).
The question i have is if i buy a X1a can i configure it to run all of the 3 networks stuff (net, mms, planet 3) or will i be stuck buying an X1i and missing out on the extra coverage that mega 3g will be offering. (which really isnt an option for me)
Any help would be greatly appreciated

I have an X1i myself and I must say the videos are very good
X1i also support 850 band..?
I have X1i, and according to the phone settings, it supports both UMTS bands, 850/1900 and 900/2100..
I have no problems whatsoever using UMTS with my provider, telenor, will try to check which band they use..

I think the general consensus is that provided there's plenty of light, the videos are good. Once the ambient light starts to drop, it's as if the camera is hardware/driver level coded to increase the exposure to make the most of what light is there. Unfortunately this leads to motion blurring.

You guys do realize that the hardware's the same and its just the ROM that changes, right?
Just get any X1 and check out both ROMs and see which one you like better / if you have compatibility issues with your carrier.

Sorry, but that is plain wrong !!
This issue has been posted many times:
the X1i is not capable of UMTS 850Mhz reception. It uses the Qualcomm 7200 CPU and has a hardware filter to prevent reception on UMTS 850Mhz (patent infringement issue). The video recording rate is uncrippled
the X1a uses Qualcomm 7201A CPU and can receive the UMTS 850Mhz frequency (Canada, USA, Aus, S Americas, S Africa etc). Video recording rate is crippled (patent infringement issue)
SE had separate factory assembly runs for the X1i and X1a to ensure this situation actually prevailed.
The X1i does list the UMTS 850Mhz frequency in the phone bands but the device does not receive this frequency. Changing ROM's does not alter the hardware limitations.
The retail price difference between the X1i and X1a is up to 50% higher for the X1a. This seems to be for the purpose of paying Qualcomm royalties to Broadcomm for the patent infringement.
I guess I really f....d up this time, haven't I?
Sorry for that then. I had a friend that bought an X1i here and went to the US changed the ROM and worked perfectly... I guess the carrier must have been using something other than 850 Mhz...
Oh well...I apologize for talking out of my ass...
Will do more research before stating something I'm not 100% sure of

x1i does not support the same 3g bands as the x1a.
The x1i is "better" because it has a better video camera, but if it doesn't work with your carrier's 3g bands then it doesn't really matter.
I am almost positive the x1i does NOT support 850/1900/2100 for 3g.

Just on a slightly seperate topics.. if 2 factory assemble both x1a and x1i, why is most silver ones which are both x1i and mostly x1a in aust have cracking issues? must have been the materials itself then..
while on the topic of the bands.. does 3 has 850 band yet? if so i can give a try on my x1i to see if it does have 850 band or not.. Optus dont use it btw..

The colour, black or silver, is irrelevant to the UMTS frequency capability. The cracked case issue is likely to be related to early production run issues, but we'll never know for certain, I think.
Which carrier is also irrelevant - the X1i will not receive UMTS 850Mhz irrespective of who broadcasts it. I have no clue about 3 except that because this small carrier is city-centred, it is most unlikely to broadcast on the UMTS 850Mhz frequency ... this low frequency high-wavelength broadcast is used in regional areas for distance penetration.
Optus uses UMTS 900Mhz, which the X1i should receive (it is "tuned" for 900, 1900, 2100Mhz), and which is OK for distance as well. But Optus' regional coverage is woeful, both for GSM and UMTS. Suits if you never much leave the city areas, of course.
Hello everyone,
This is my first post. Anyways, I have searched the forum, for this answer, but could not find it.
I understand that the X1a will be best in the US, as I understand it, because the network I will be on, AT&T, will be expanding their network to the 850MHz band. OK, well what I need to know is what kind of connectivity I should be expecting outside the US.
My new extended international family is all over the world. I don't travel real often right now, but I will be traveling more frequently over the next few years.
As I understand it, in the major cities in the US, the X1i will do fine on AT&T, as they have 3G on 1900MHz, but again, only in the big cities. This would be fine with me, I just don't want to be screwed as I move beyond the cities when traveling in the US.
So, for my situation, what is recommended? I fully understand the differences between the models, I am just not as familiar with the networks across the world.
Thanks,
-Steve
You should be able to get GSM reception world wide (quad band GSM) on either phone.
If you want 3G reception in the US go for the X1a, it also has UMTS2100, so you will be able to get 3G reception in many other parts of the world too.

Is that a garaunteed 3G Freq in the rest of the world? Can you give examples of where it would be used? or is it like 1900 in the US, where only major cities will broadcast on that Freq?

I know for a fact that what you just said is wrong, there is a hardware difference. Specifically, the radios are different.

The English version you linked to is indeed the X1i (900MHz), and not the X1a (850MHz).

I recently purchased an additional Xperia, an X1i, to test 1900 MHz 3G proliferation in my part of the world.
In most of the area that I live, work and travel, the X1a got a perfect 3G signal and the X1i would only get EDGE. The only place the X1i picked up a truly usable "H" signal was in DC itself. As soon as I got outside the DC metro area, the phone would start using EDGE. Even if it showed an "H" it would immediately move to EDGE when I started to make a voice call or when I started to use data.
I do not think that most users of the Xperia are going to be happy unless they have an X1a. If you live in a metro 1900 MHz area that was developed in part of the older AT&T 3G rollout and you will seldom leave that metro area, then perhaps the X1i will work for you. Otherwise, I think you should spend the extra money for the X1a.
As for your overseas travel, perhaps people could be of a little more use to you if you could tell us what countries or major metro areas you'll be travelling in.
Most of Europe is using the 2100 MHz WCDMA frequency, if that helps. Your US edition X1a would work fine on that frequency.
http://en.wikipedia.org/wiki/UMTS_frequency_bands <--If you scroll down you will see the UARFCN settings for the UMTS frequencies. If one of your friends overseas can use fieldtest.exe from a Windows Mobile phone, they can check to see what channel they are on. I know the UARFCN will show up in the "3G Neighbour" screen. Cannot remember if it shows up elsewhere.
Hi,
I currently live in the UK and I will be moving to Australia in a few months.
I'd like to buy an X1 but even after spending hours on the net trying to find an answer, I can't decide what's the best version to buy to enjoy 3G in Oz and Europe: X1a or X1i?
I will be living in Sydney, but ideally I'd like to have good 3G coverage in all major east coast cities (X1i 900MHz OK?), and possibly in the countryside (X1a 850MHz mandatory?). It's also hard to tell which network provider is best (coverage, price) when you don't live there...
Please could you give me your opinion?
That would be great if you live in Australia and can advise accordingly
This post and the associated thread are good, but I still can't really decide: http://forum.xda-developers.com/showpost.php?p=3409009&postcount=15
Many thanks in advance,
Seb
I was in Australia 3 weeks ago and X1i worked just fine there. No idea about 3G, but I would say it all depends on the provider and how well they cover it.
Both the X1i and X1a work here, but on different networks. Our largest provider Telstra uses the 850MHz band so you will need an X1a for them. You can buy an X1a on contract with them. Other providers like Optus and Vodaphone use the 900MHz band so you would need an X1i for them. Optus is just about to introduce an x1i contract (I think). Telstra is supposed have the most extensive coverage, (out bush) but I have an optus service and live in the country and their coverage is fine. In terms of cost of service Optus cost a way lot less than Telstra. The main telco forum site here is whirlpool.net.au. It will give you a good flavour of what, what's good and what isn't.
Oh one last thing … you'll pay a lot less for an X1 purchased outright in the UK than you will here in Oz.

Thanks a lot, very useful information!
You'll need to consider which carrier you join very carefully. All carriers use 2100MHz WCDMA in major cities and suburbs, but outer rim suburbs and rural areas will use 850MHz (Telstra) or 900MHz (Optus & Vodafone). There is another carrier called "3" but they only have a small metropolitan 2100MHz deployment and roam on to Telstra GSM (not 3G) at the same call rate for the rest of the time. (However, data is charged at a different, exorbitant rate.)
Telstra is the most reliable, but the most expensive- any other 3G data carrier is likely to be completely overloaded at peak times, depending on where you live. Optus is popular with the younger population because they have the best prepaid deals (possibly the best medium to heavy use data + calls deal around). 3 is also popular with that demographic because they offer decent call rates and a large amount of free minutes between their own customers, however bad for business because of issue with data roaming.

All carriers use 2100MHz WCDMA in major cities and suburbs, but outer rim suburbs and rural areas will use 850MHz (Telstra) or 900MHz (Optus & Vodafone). There is another carrier called "3" but they only have a small metropolitan 2100MHz deployment and roam on to Telstra GSM (not 3G) at the same call rate for the rest of the time. (However, data is charged at a different, exorbitant rate.)
Telstra is the most reliable, but the most expensive- any other 3G data carrier is likely to be completely overloaded at peak times, depending on where you live. Optus is popular with the younger population because they have the best prepaid deals (possibly the best medium to heavy use data + calls deal around). 3 is also popular with that demographic because they offer decent call rates and a large amount of free minutes between their own customers, however bad for business because of issue with data roaming.

Thanks for the additions.
I kind of made my mind to get the X1i and I will probably get an Optus pre-paid once I get there.
