Sony has promised a lot of thing in the past. A lot of flips from this company, I bought a lot of it's phones: W660, W850, G900 and Xperia X10. Honestly the best was w660 and w850. G900 was a scam, as the software dev was stopped almost immediately, you cannot find apps for it, the engineer that designed the touchscreen hardware contacts should be shot, my touchscreen broke and I had to replace, I bough original one and it didn't really fir 100 percent you had to push on the screen to make contact, I had to buy the entire case to fix this, also the protection from software ver to the next made the phone very hard to crack and without that they were pretty lame, the X10 is ok if you can go without a good ringtone ( speaker sucks ), the sound in the phones is low ( bla bla EU regulations ) the updates come very late and they are intentionally left out for the X10i so you should but the Arc or S, Ray which almost have the same hardware. If the guys at XDA ported these why is Sony not doing it, oh because they want to squeeze more money from you. I said a long time ago that I will leave Sony products and I will, more and more they seem to me like they are scamming me.
