I have the WT19i with exactly the same Phone Software Version:
1250-5829-4.0.1.A.0.283
GENERIC-user
File System Version is only different (i)
WORLD-i_4.0.1.A.0.283
I think the software version you can use works on both models. The difference for (a) and (i) is only the radio air interface software which is a different file.
Nobody knows if upgrading software provides any improvement. I mean to say nobody is able to post the information. You still have to fix the magnetic sensor file yourself in LWW if you want a properly working compass.
They might fix this in ICS, I don't know.

Unlock Bootloader
To update your device needs to have the unlocked bootloader. After that you prefica find a firmware compatible with the version after that seek a stable kernel that works and endanger your cell phone to do the update. Several improvements can exister ROMs prefeiro modified but still I get the original version that came only with the Sony Root is already very good. From clocks to not very high because I have not tested. Some kernel as the kernel if I remember correctly Rage comes up 2.0 Mhz But nYou need of a look at this link http://unlockbootloader.sonymobile.com/

ok so if i want to update my phone this week i need an unlocked bootloader if not i'll have to wait until september to upgrade (it's the date that Telcel say for the ics upgrade) :S the only hard thing is to find an "a" frimware i always find "i" versions

Incorrect. Updating requires locked bootloader.

First, backup your current firmware. You would need this if you phone will have problems w/ reception. Follow this video tutorial.
But, I don't know where PC Companion stores the downloaded firmware files yet. I only know Update Service. Don't do anything yet if you don't have a backup of your current firmware. Maybe someone here knows the location of the firmware files. I'm using repair option in PC Companion right now to test but I still can't locate it as of now.
Ok I GOT IT Use repair option in PC Companion.
In Windows, show Hidden folders.
Go here:
Local Disk>Program Data>Sony Ericsson>Update Engine>db>"open this folder">blob_fs
Now you can follow the video tutorial..
Anyway.
If you're done w/ the backup of your current firmware,
try Generic US Firmware. It's also WT19a. Based on this list.
CUSTOMIZED US WORLD A 1254-1956
Change your CDA number in build.prop using this tutorial.
Use Root Explorer. Go to system>build.prop. Mount R/W.
Open build.prop w/ text editor and replace the following w/ the US CDA:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Save&Exit.​
Now repair using PC Companion. NOTE: You'll loose root access coz it'll update you to .62 (as of now).
Check your 3G/HSDPA signal if it works..If you're having a problem w/ reception, then you should go back to your original branded firmware by flashing the backup you made.

It's okay. You can try to flash any .58 WT19i firmware and afterwards, you will replace the CDA remember?
Try this WT19i_4.0.2.A.0.58_(1254-1868).rar
And once you repair it via PCC, it will be replaced with an updated US Generic Firmware.
Besides, you already have a backup firmware if anything goes wrong w/ your 3G/HSDPA signal.

ok i'll try it then i'll tell you what happen
But i still asking me why the PCC/SUS didn't let me update qhen i change the CDA number, i remember than in mi x8 i did the same and it worked, but i remeber that first i uninstalled all the garbage of telcel...
can it be that something of the telcel garbage "apps" it's blocking me for update?
second i still downloading all the things i need to flash the frimware, but do you really think that will work changing the CDA? until now it didn't work :S
Well i flashed with that frimware and changed the CDA now each time i put in the PCC repair the phone shut down :S and i don't know why :S
