I have a Bold 9700 for AT&T. I wanna purchase the app 'MP3 Ringtone Creator" but when I click purchase, it tells me to sign it, i put in my password and it tells me "an error has occurred while setting up billing through your service provider. Please try again." and I deleted and reinstalled Bb app world twice, and it still tells me the same thing. I really want this app, but it tells me that for very app i try to buy. I have it set so the bill goes to my phone bill and thats how im gonna pay it. Help please! 10 pts to the best answer!
