I recently got a blackberry 8100 from my brother because he upgraded. I was looking at my friends 8100 and on his browser he has an arrow as a cursor I just have a flashing box, I want to know if this is because my software is out of date? I have 4.2.1.109 which I downloaded from the rogers.com website. Also before I installed that I wiped my blackberry. Anyone have any applications they suggest I install?
