I'v always known that magnet's are not good for electronics. However i just got my HTC hero, and i want to try to prevent this dust problem im reading about from hopefully happening to me. I have the screen protector on the screen, and a rubber/silicon case from sprint, but i dont have a carrying case that clips on your belt. So i either have to carry the hone by hand or put it in my pocket.. Since the pocket is full of lint thats a bad idea.. However all the cases iv been looking at have magnets to close them. Will this hurt my phone ? Also which holster do you guys recomend that is big enough to hold the phone while its still in the silicon/rubber case.
