Ok well i recently purchased my Vibrant on Oct. 1st. Under firmware version it says 2.1 update 1, which it came with out the box. Now i read online that there were two updates, the J15 and recent J16. From what i've read so far people who have updated, their firmware version now says 2.1 update 1, like my phone. I was wondering how do i figure out if i have J15 or not? I know i dont have J16 and haven't even received a OTA update for it either. Would the updates show up on the last 3 letters of the baseband cuz on mine it says JFD which from what i read was the factory setting before the updates. Also, if it turns out im running the factory non-updated settings, how do i get the update? Are the OTA updates regional? Any help would be appreciated.
