I have had my Blackberry Curve for a few weeks now with no problems. All of a sudden today any time I try to open any of my messages (email, VM, text) it won't open them. It will unbold them like they have been read, but I can't actually open them to view them or respond. I don't think it it my track ball because I can click on other applications like facebook and go in and open other things. I am not sure if maybe I clicked something somewhere that disabled the ability to open messages or what. ¿Alguna sugerencia?
