Hello all, I have a iPhone 3g with an Incase Slider, which looks and feels great. I am looking for a top load case/pouch that will hold the phone with the slider installed so I can carry the phone on an equipment bag while working. I have found a couple of "universal" fit cases that will suit my needs, however, the cover flap is held closed by a couple of small magnets. My question is, will these small (about the size of a nickle) magnets cause any interference or other harm to my phone? I know that magnetics and some types of storage media do not mix, but I'm not sure on this one. Any input, other ideas, or info is much appreciated. Thanks in advance for the help.
