Sony Ericsson XPERIA X10 GSM Smartphone with 8 MP Camera

Sony Ericsson XPERIA X10 GSM Smartphone with 8 MP Camera. Excellent phone. Cover my expectative. Android is an excellent system. The only problem is the version of the system.  This phone is great. I got it free from BB and it rocks. I have to say it's my first Android phone but I love it. Huge and sensitive screen at 4", great camera. I'm running A 1.6 but Sony has an upgrade to 2.1 that I'll install ASAP. Love this phone, becouse :

1. The real phone model is x10i (which I guest i stand for "international" version)
2. After received, I install Sony Erricson PC Companion Software which will allow me to upgrade to Android 2.1 update 1 
3. Phone look nice, compact (compare to other phone same class); however the back cover made of plastic, which makes it look cheap!!!.
4. Screen protector also included (even x10i screen is anti-scratch) 
5. Phone works as I expected, pretty big screen, vivid color. 8.1M camera with smile detection, and other features seem nice to have. 
6. Take me a while to familiar with phone behavior, but once I get used to it, I like it. 
7. Virtual keyboard is nice in landscape mode, but difficult to use in portrait mode. 
8. If turn on WiFi, battery will be drained for a day, (but the same for Droid 2, Droid X). Turn off Wifi, it may last for 2 days. Set screen brightness to lowest level may extent more, and you can adjust its brightness by using widgets short cut. 
9. So far, I will happy with this phone!
10. Without warranty, it might be potential problem!!!
