I am sending back my W850i I have had a few problems with it dropping calls which I think is down to 3G network. How ever when I was in the states worked perfect. You can turn this feature off but I dont think it is any improvement over the W810i which I still have. The camera on the W850 is no where as good as the W810i.

I am getting a samsung D900 which I no I will regret but I did try it with the X5 and it worked. Dont think I will get text messages on the nav, But no big deal really.
