Can i flash st18a with this one>ST18i_4.1.B.0.587_CE_1252-3693?
If not, where can i get st18a stock firmware?

I don't think there's a significant change.

Where exactly are the differences noted? Does it affect ability and accessibility to get 2G, 3G, or 4G frequencies?

You can check gsmarena for the specs: http://www.gsmarena.com/sony_ericsson_xperia_ray-3972.php
As far as i know, you don't need to worry about the firmware, as there doesn't appear to be country or carrier speciffic versions of the baseband.

Yes, but the ST18i and ST18a are different precisely because their hardware (radio) can only operate on certain frequencies, i.e.
3G Network
ST18i - HSDPA 900 / 2100
ST18a - HSDPA 850 / 1900 / 2100

Ok, so the X10a kits are finally starting to roll out.
I am running an X10i rom (Wolfbreak) on my Att X10a and I was thinking of flashing X10a AM-US GENERIC 1233-8200 but then I thought of something...
If kernel and baseband are the same what is the difference between kits?
Just some lines in build.prop and different bloatware?
If I knew all of the specific differences and none are baseband or kernel related then I could put together an xrecovery package to X10a-ize my rom and not have to mess with flashtool again and hopefully keep root and the tweaks,etc. (not to mention my user data).
So what are the specific differences and would that be possible?
If the baseband and kernel are the same, then it is basically pointless
Then why bother with all these kits?
To change some lines in build.prop and add different filler apps?! Are there no area-specific frequencies or channels or whatever that need to be defined?
And I am correct in saying that the kernel & baseband are identical, right?

Yep they are..
X10i = HSDPA 900 / 1700 / 2100
X10a = HSDPA 800 / 850 / 1900 / 2100
Hardware is the same but the baseband is different in the sense that certain frequencies are disabled and others enabled this saves battery power in terms of scanning.

That is not at all correct. .
It is the hardware that does this (the radio) the baseband is not changed
The two phones have different hardware (internal radio)
Indeed they do, my mistake. You get a cookie
Almost
You guys almost got me all excited. I'm on a third party carrier with an x10a that uses T-Mobiles network. Almost had me thinking there could be a software work around to get 3G out of it. Oh well.
Hi guys,
I am using 77.30P radio in Brazil and having problems with the signal, the carriers here are a mess, the same carrier uses from 850mhz to 2100mhz...
My question is, what basebandd (radio) can i flash which uses all those frequencies?
If someone can help me out by pointing the know frequencies for the most common radios available it would be of great help!
Thanks in advance
All AT&T radios can use UMTS (3G) 850 and 2100 if I recall correctly.

Do you know where can i find that information for sure?
If this issue is not related to baseband, i have to start looking somewhere else...

Google what bands does AT&T use for 3G. But as I said, I think it's 850 and 2100.
AT&T uses the 850 and 1900 bands for 3G. As for the radio version, use the one that came with your phone. The atrix supports W-CDMA 850/1900/2100 for the AT&T version but mine in addition to those listed above, supports the 900 band as printed on the box.
... In the AT&T and International versions of the Atrix... why can we not enable HSPA/UMTS on 900MHz through flashing radios or other software means?
Edit: Phone is an unlocked AT&T version on O2 UK with O2 sim.
Because the 900MHz band that the Atrix uses is part of the quad-band GSM, which is 2G/EDGE, not UMTS. Those are two different standards.

But the international supports UMTS/WCDMA/3G/3.5/HSDPA/HSPA/HSPA+ on 900mhz going by all of the spec sheets I read.
UTMS is 3G. HSDPA is 3.5. A standard of WCDMA. HSPA is another WCDMA standard which again is a 3G Technology (3.7G?)... Either way they all come off the same 3G cell
Atrix International: GSM 850 / 900 / 1800 / 1900 | 3G Network HSDPA 850 / 900 / 1900 / 2100
Atrix AT&T: GSM 850 / 900 / 1800 / 1900 | 3G Network HSDPA 850 / 1900 / 2100

Same hardware. Why can it not be enabled?
I don't know about the other bands but you specifically mentioned the 900MHz band so that was what I was talking about.
More than likely the carriers have locked the radios and/or hardware. It's like other carrier's world phones will not work on AT&T/T-mobile, even though they technically can support those bands.

Thing is, its an unlocked AT&T phone on O2, and I want to take advantage of their new "Superfast 3G 900" network..
Maybe I should have made clear in the first post... woops.
Okay, the first two links do not show any proof they got it working on UMTS 900MHz band.

I wish I could help. I'm not saying it's impossible but as far as I know, 3G (HSPA/UMTS/WCDMA) can't be done on the 900MHz band if you're using an AT&T Atrix.

There doesn't seem to be any logic to why other than software as the radios taken out of all firmwares work on both versions. The only logical answer is software (if I could SBF flash a UK firmware, not CWM that would help, but there was other differences with the mainboard right?), or its the same chip just slightly modified without that band included.
I was mooching around system folders trying to find anything that could give me a clue, but to no avail.
I think it has something to do with what module is used, which is a hardware component. I know the AT&T Atrix uses the Qualcomm MDM6200 but I have no idea what other versions use.
I might be wrong though.

Indeed, so logic would say that if we flash international radios for a different module (if they are different) would soft brick the phone or cause the phone to no get any kind of reception what so ever.
I do find the international radios and att radios (other than the stock and 1.87) make the H+ signal level not go over 1 bar.
I'm not sure about bricking the device but I know they usually have those radios locked down pretty good which is why most people need to buy unlock codes or get their carrier to unlock their phones for them. It's not very common that end users can crack them.

SIM Lock and Radio locks are two completely different things. SIM locks are easy to break with a £10 note and a guy with some device, a radio lock is more difficult we dunno if its hardware or software.
Has anyone got an international/uk/europe Atrix that they'd kindly tear to pieces to see if its the same cellular modem?
i'm unable to use 3g/umts on my current carrier due to the freqs differences SK17 uses 850, 1900, 2100 and SK17i uses 900, 2100...
my carrier is on 850/1900, there's any way to flash/change the radio (or baseband) to 850, 1900, 2100 on a SK17i model??
I bump, therefore i exist...
Dude, had you tried to change your apn? I am almost sure its an apn problem. Both phones are quadribands and by that they should work within any Carrier you choose.
Sent from my SK17a using xda premium
SK17i type phones have 3G chip, that only uses specific bands, SK17a type phones another type chip.
You can't change that. If your shop sold this, you might go back to the shop and explain to them, they should change it for you, if it doesn't work in their region.

APNs only control 2G/3G/HSPA internet usage and where to connect. APNs are not related to 3G bands.

Thanks, but i don't really know why SE would make to almost exact devices, only with that difference, although they've done it before... -.-"
i got a motorola defy, and you can change the baseband (and the 3g/gsm freqs with it) so easily, there's an app, you just need root, in cm7 it's even on the device settings...

An app cannot change the baseband. Currently, it can only be done via Flashtool and official programs(Update Service).
At least, not on Xperia phones.

The frequencies cannot be changed. If the phone is set to work on these frequencies, it will work so.
Phone, which is made to work on 900/2100 Mhz, cannot work in 850 Mhz area, because the chip hasn't been built so.
Is there a way to enable it, or the hardware is missing it?

900 is the GSM network, it IS enabled. there is no 900mhz 3g.
and if your trying to get 3g on a Tmobile banded network. Im sorry but you sir, need to search. or get flamed.
My carrier uses two frequencies for 3G: 900 and 2100.

If it's not supported by the phone already then no you can't, searching would tell you this
