my friend just gave me his old blackberry, and i've been having some issues. i bought an app and it completely loaded and tells me its ready to install and then it just stops and wont install. i tried downloading some free apps and it is doing the same thing. i'm just upset because i've paid for an app and don't know what to do. it also wont let me delete "archived" apps that my friend had before. please help! i'm new to the blackberry world so have no idea
