Hey guys

I've been having this problem ever since I got the phone and it seems to be a slowness arising from the use of bb app world. It probably has something to do with it continuing to load the page data even after I've stopped using it, and the slowness progresses for a long time but never when I download and install applications; only if i browse.

Each time I'm done browsing, I've had to reboot the device by taking out the battery. Does anyone know of a fix?
