Hi
I bet with betwinner bookie with mobile app and they limit me ,
If i clear app data and change my ip can create new account or may be they record my phone mac adress?

They can not detect the physical MAC adress from simply using their website, that's technically impossible.  I would reset the phone to factory settings though to be sure everything is gone.

MobileApp is mobile website or application downloaded from store or their website?

In application they can have much more information to identify you.

application downloaded from their website

In that case do not risk it and use a different phone.
