im expecting a Sony Ericsson Xperia x10 (previously known as the x3) tomorrow, so if anyone has any questions feel free to ask. It will have the US tmobile 3g bands, and will be running android 2.0. Its still in pre-production but I managed to get my hands on a retail model. The ones you see in reviews and videos are prototypes which are running android 1.6, the retail will be running android 2.0, which is the one I will be getting. Its expecting to release in UK in 2 weeks, and in USA in about a month or two. There aren't many reviewers out there that have a retail model so if you have any questions that you couldn't find answers to, feel free to ask. Ive owned an n900 before so I can do a fair comparison. Ill do a little review once it arrives.

Heres what it has:
1ghz snapdragon processor
8.1mp camera
4'' display 480x854
slightly thicker than the iphone (which is very thin IMO)
runs android 2.0 with UXP (sony's customization, like htc sense)
and your typical wifi bluetooth etc....
