I have Blackberry Storm 9530. I bought it unlocked so that I can use it with mm T-mobile contract. But today the screen is behaving very strangely. Whenever I am touching it, it is not going to the option that I am choosing. I am quite new to this phone and am wondering how to fix this phone. What can I do to fix Blackberry Storm touch screen problem? Do I need any software upgrade to fix it? If yes, then how could I do it? Please help. Thanks.
