So far so good! Use Samsung Kies for latest firmware updates since OTA updates aren't official anymore.

Summary: So far the sgh-t989 is working great. The phone came with gingerbread android installed but was able to update it to version 4.1.2 via Samsung Kies ver2 (free download from Samsung website). The radio, transceiver, bluetooth radio, wifi and cameras are all in good working order.
Summary: Just as described. It came on time, brand new in a box with protective tape all around the phone and screen. It was network unlocked like it said, and in less than a month from writing this review I am going to purchase another one. It came with Android OS 4.xx
