Re: [Cingular] Magnetic closures on cellphone cases
"It reasons out, then, that perhaps moving the phone past this strong magnet in the case (less than a millimeter from the phone's already slender housing), could induce a current in the signal line from the phone's slide mechanism.
That's my wild-assed theory"
wes,
Close I think but almost all sliders and flip phones use a reed relay that is actuated by a magnet in the flip/slide or visa versa. Anyway the reed relay contacts are magnetic polarity sensitive. One being held close can easily be opened by an opposing slightly stronger magnet passing closed by. The chance of doing any electrical damage as in an induced voltage in your phone from the magnet in the case is very slim but if you pass the reed relay past the case magnet the chanches of bumping (tripping) it are pretty good. Reed relays are used because the are very sensitive and very fast acting.

| Not sure about your "switch toggling" problem.
Take note that all Blackberries have a feature called "In holster" mode or profile. The magnet in the holster forces the phone to switch to a different ring/vibrate profile. This is useful for situations when you don't want the ringer to go off, instead it will vibrate. This was designed for business users who don't want the ringer to go off during a meeting. On a Blackberry you can also set it to answer when you take it out of the pouch. The magnet answers the phone when removed from the pouch.

| spamd,
I was not aware the Blackberries had such a feature. That puts a wrinkle in the magnetic holster selection that I would not even want to mess with.
Sounds like if you own a BB you had better buy a case certified for use with a BB or you could find yourself having a lot of strange problems. |

Thank fully, blackberry sells all their models with their own magnetic cases / clips specially designed for such purpose
