I just got the xperia x10 last night. Although it has 1.6 I really like it. I know I can manually install 2.1 but I'm really scared to brick my phone. Yes I'm a big chicken.
Samsung Galaxy 5 (GT-i5503) my main touchscreen phone accompanying my 8520's (Physical Keyboard--on phone--is not really my type so I get myself an android device)
