This is a new feature that came with the upgrade of T-Mobile Mall. It is where you can purchase, ringtone, music, caller tunes, and listen to streaming radio. You will not be charged for anything unless you choose to make a purchase.
I have Music Hub right now and it's asking me to sign in with my wifi credentials or disable wifi in order to view my purchases on my Huawei mytouch phone. The problem is that my wifi isn't on at all right now. please tell me how to fix this or just get rid of this feature. I'd rather use the old t-mobile mall.
