I have read these forums for a long time and felt compelled to ask this question. So I registered and this is my 1st post. Also I did a search and it didn't really give any information.
I have a magnet on my PDA pouch and it seems to be a pretty powerful magnet and was wondering if it would damage my phone in a bad way.
Depends how strong the magnet is. Very strong magnets will affect any type of electronics case in point EMP. I wouldn't be too worried about it if its just the one from your case/holster.
