Do you know if the one due for the US release going to have wifi?
Haven't received any infos yet.
And two more questions. How is the screen? And how is the battery life? Thanks
The screen is just great. If you know the i320 screen, it seems to be the same. Bright and crisp, as all Samsung phone screens are. Basically (IMHO) the best a mobile phone can get.
It's too early to talk about battery life. Please keep in mind it was an early development prototype only, so I cannot say too much about the battery life yet.
1- Is the processor TI 200MHz like the one in most SP's? (ie. QTEK 8500)
Similar. It's a TI OMAP 1710 CPU with 220 MHz
Is the UMTS/HSDPA band on the i600 work in North America?
No, AFAIK it's single band only (for the i600) which is another reason why we will see the i607 released in the U.S.
Yes, it feels a little bit heavier but not too much. It doesn't bother in the pocket.
