I will see if it works with Chinese sims as well (I had to add a "hypersim" over my sim card).
But no reason for that stuff not to work either.
If in a Wifi environment, it is an amazing toy. I haven't tried it in GPRS yet.
But honestly still don't like the not super accurate virtual keyboard. I guess it will come after using it for a while.
Oh, and "my" Samsung i600 (my previous phone) is not for sale. I gave it to my wife. She thinks it is more "professional" than the Motorola RAZR she had.
So it is.
