    I ordered a case from Top Quality Cell Phone, PDA & Ipod Accessories. The specific case, see here, is advertised as a) being for the HTC EVO and b) coming with a magnetic latch.

    I received the wrong case - it has snap closures. I sent an email requesting that the proper case be sent and I received the following reply:

    [FONT=&quot]The EVO can not use the magnetic version, it affects the operation.[/FONT]
    I suspect that this is nonsense. Can some one please let me know if a case with magnetic latches can be used.

    I use a leather holster that uses magnets to keep it closed. HTC makes a leather holster that Sprint sells and I'm pretty sure it uses magnets also.

    There is a possibility, however, I am skeptical about their answer too.

    HTC Evo's have a capacitive screen, which works by detecting disturbances in a electrostatic field (here is a write up I did on PPC Geeks PPCGeeks - View Single Post - Capacitive Screen vs Resistive Screen)

    Theoretically a magnet could also disturb the electrostatic field and change the "capacitance" readings. Meaning, the phone screen will think you are interacting with it when in reality it is a magnet in close proximity. If you just power off the screen before placing in said holster, there should be no issue.

    I believe that magnets are the basis for the new Capacitive stylus that are being made.
