Tried both cases and in both it's just a normal app with sb login screen added. Behavior unvhanged. My suspicion is that some of us have not meddled with root and the mod works only if the phones were deprived of warranty
Also, each time i attempted to download the app here i had to pay sb coins so make sure you don't double harge for something that doesn't work, kinda uncool
No I just Downloaded it from the site my first choice cost gems but the ones after didn't it also took gems for me to unlock hairstyles and outfits. Sorry thats not really helpful I know.
