I want to upgrade to 1.5, and as I currently understand, it is different depending on what region my phone is, and whether it is software unlocked (hacked) or purchased unlocked.
How do I know what I have? The seller doesn't seem to have a clue, other than it is "unlocked everywhere".
Current info
Firmware version: 1.0
Baseband version: 62.33.20.08H_1.22.12.29
Thankful for help, don't want to brick it the first day...
