I've seen some old threads about magnets and the iPhone 3G but not much about iPhone 4. I know an iPhone is an iPhone but I was just wondering if anyone has used a case with magnetic closure and if they experienced any problems. I did see an actual apple document that talks about it possibly messing with antenna reception. I just got a leather case on Amazon and I love it but it had magnets. It's not worth it thoughi if there's a chance of it screwing up my iPhone. Anyone have any help?
