Hello justme,
The authorized service center of Sony Ericsson in Greece, that I visited, claimed there are major hardware differences between the mobile phones sold inside and outside E.U and even if it is the same model (W810i), it's totally incompatible with their firmware, which is why they don't accept to even take a look at it with or without warranty (they even refused to check it under some charge).
I believe that's completely false, as I had flashed MAIN+FS 7 months ago in order to change CDA from ASIA to MEDITERR in order to add Greek language and it was functioning fine. When I get a chance, I will e-mail Sony Ericsson in both countries to find if that's an official policy or something that the specific service center made up (although I don't see why they would do that, as I even kindly offered to pay for a hardware check).
Regarding the download area, I am really sorry for disturbing you about it. Obviously I was sleeping on my chair last night if I couldn't see the [+] in the right side that I had to click, which I had clicked before.
Special thanks about your recommendation to not attempt to flash my new phone, but after seeing SE's dumb policies with W810i and since W960 already has my native language, I was not planning to do anything that may give them the chance to claim that warranty no longer applies.
W960i works smoothly and I'm really impressed of it, currently in research of applications and customizations to make my life easier. Although I have to get used to it since I am still so addicted to my W810's menus and keys, hehehe.
Thanks again.
