i dont belevie in cases i belevive its safer in ur pocketIs it true that using a leather case with magnets as lock can harm a mobile phone?
I've had the same concern, but since many phone manufacturers sell such cases, I would have to say no.





If it were only aftermarket suppliers selling them, I'd stay away from them, but even Palm sells them for their smartphones. I would HOPE they've tested them!
