Wifi only works the internet browser on Blackberry but not apps?

the internet used to work both my phoneline and wifi, but then my phone busted for a while and when i got it back three months later, the internet on the apps won't work - only the internet browser. not even my blackberry apps world where you download apps works. like the program itself works, but the internet won't connect to it.

does anyone know how i can fix this?

thanks
