Xperia Ray :: Can't Update To ICS

I want to update my Ray to the new ICS, but everytime when I launch PC Companion or SUS, it said me, that I'm with the last update(2.3.4 - Build number 4.0.2.A.0.69). My SI is 1252-4364.2, and it isn't listed in the SI list for now, I don't know for what region is it that SI, but my mobile operator already launch the release.The update here in Bulgaria(with thoose that are with Mobiltel for oprator) reseaved the update in the late April, I still haven't it.. So is there any chances to update the phone soon with PC Companion or SUS, or should I use flashtool(I don't want to loose my waranity either).
