yup, silly was right. i once jailbreak my ipad to play pokemongo without going outside and i manage to collect all pokemon around the world.
the problem is my ipad gps or location are broken and i'm stuck with gmt0 (london) so my match timing got stuck there.
in the end i have to unjailbreak and restore my ipad to factory default in order for my location to be correct to the country i am located
