http://androidforums.com – Hi all, i'm new here and to pretty much all things galaxy s3. I bought a galaxy s3 i9300 32gb factory unlocked Phone. It doesnt seem to be routed but has developer options in the settings menu. everything on it works, i have no issues but i have the 4.0.4 ICS. FWV PDA:LF2 / PHONE:LF2 / CSC:LF1 (OPS) now this doesnt have the volume slider on the drop down. Its meant to be unbranded i guess as its factory unlocked but when the phone starts it hs the "YES OPTUS" Logo which is an australian model i think. It does work on vodafone, t-mobile, o2 sims as i have tried them so far (General)
