Also guys, stop misrepresenting the local/export set issues. The only thing local sets have on other sets around the world is local warranty. For the hardware, you are getting A3003, the global model. This is the exact same phone you can get from HK, UK and Europe. If you want a 3-pin local plug, you get exactly the same buying from HK and UK. I'm not sure which model the local resellers have but do check. The global model (A3003) covers bands 3, 7 and 8 (only Singtel), currently the LTE bands in use here. You would want to avoid the US model (missing band 3). With China you can flash OOS but you miss out on band 8. So if you have your methods to get an OP3 from HK/UK and don't care about having local warranty, then do so as it's cheaper.
Also received my Orzly fusion bumper case (from Amazon). Nice case! shows off the phone, has a lip around the screen and the back is juuuust higher than the camera.
