Go to options, advanced, service books. then, in landscape mode show keyboard (full keyboard only) then enter the !?123 key, 4, !?123 key, ?, !?123 key, 2, !?123 key, ?
Try it more than once, I don't always get it the first time.
and the wifi service books only go on BB's with wifi built in, and I seen them load and stay, on the storm 2 9550. Just used my own books with out any wifi. The wifi seemed to only work with the BB browser, not the cricket browser. and vice versa. Feel free to ream me if I'm wrong. Just what I saw with the storm 1 and 2, have never worked with any other BB's.
