Depends on which model you have (Sprint, Verizon, AT&T, T-Mob, WiFi, GSM Unlocked). Right now only the Sprint model has an officially released and OTA transmitted GB update in the US. With the others you either have to take a wait and see approach that the carriers or Samsung (in the case of the wifi and unlocked models) will actually release an update at this point (doubtful given Samsung's focus on their numerous Honeycomb flavored models) or take your chances with a custom GB ROM port.
