Yes, you can use SamWP8 Tools or WPH Tweaks for change Phone Mobile Operator Name for 000-AT, with this, you can check and install GDR3 update without Hard Reset.
Thank you very much for your time and response, I really appreciated it. But now, since I had read a few more info on these "Interop-Unlocked" stuff, will this "Official GDR3" block the Samsung diagnosis app (##634#)? I notice I have a shortcut to the Samsung diagnosis app when I first access it, does this mean my phone is "Interop-Unlocked?" Or how do I know?
So I guess what are the "Pros" and "Cons" when upgrading to the GDR3 update, what will be blocked such as registry editors apps, or other hack apps?
Again, Thanks a lot for you help!
