I just bought the aquarium for android but after following instructions, press and hold anywhere on main screen, select 'live wallpaper', woops, there is no live wallpaper option on my X10?
xperia x10 does have that option, here is how you get it! go on your knees and beg to get android to 2.1
thats how your phone will be able to do LIVE wallpaper.... and remember anything that crosses your mind about the xperia and a missing feature do the same troubleshoot, 95% of our problems are android 1.6 
I had an idea that was the answer before I asked it, grrrrrr
Hmmm, thanks for the info...
Does SE actually know how far behind they are with what could be a great phone or is there and underlying problem we dont know about?
its just bad management, some people need to get fired. they have three operating system that they are focusing on android, symbian, windows thats why they suck in all three. the latest is that they are having problems with the HD 16 million colors upgrade. i dont think you will see an update before november.
Justin temberlake has a 2.1 on his experia, perhaps he can have better answers for you! what ever BS SE gives you my advice to you is don't believe it. do homework and find your next android phone! the best company so far is motorola they really stood up for their customers when they had slight problems.
X10 was new, full of promise...ok, yes, I'm a fool for believing anything I guess 
i went back to Nokia after a bad 1yr SE contract, but being the fool I believed SE had a great phone...
Next time check, HTC, Motorola had 2.1, why did I get fooled by the SE 1.6?
trust me your not the only fool, we all are! we had faith SE would be focusing on the xperia! i mean do you remember last year all what they talked about is the x10, after it was release, we heard from them once or twice. i am just waiting for a crazy hot phone from any company, any phone will be better than you xperia as now most of them have 2.2! there is even a knock out iphone chines m9, that 2.2 hahaha this is funny.
I believe SE short-changed us, the customers.
However, I also think that many X10 owners have unrealistic expectations.
i'll shut up if you give me 2.2 and fix the volume problem! too much to ask?
lol...
I do not have the volume issue, so can't help you there. As for 2.2 upgrade, you can stop waiting now. The chances of that happening is less than 35%.
