im going to start working for tmoblr and im getting the blackberry 8800 but im wondering how is the keypad. is it cheap like 8100 or strong like 8700? also how can i put ringtones? does it take mp3 ringtones and any good programs or mods out?

stronger like a 8700, full QWERTY keypad.

Ringtones via a website or transferring on your media card via Media Manager in Desktop Manager or just moving on your PC if you enable it as a mass storage device.
