Pouches with magnets can cause all sorts of problems, in addition to unintentional presses while trying to get the phone out.
I would get a spring lock holster. Verizon has one now. A better one is the spring clip holster made by Seidio
. It is not yet available, but they informed me that it should be available in early November. I had one for my xv6800 and it worked like a dream. It's better than the Verizon one, IMO, because it has a spring assembly to hold the retaining piece in place . . . better than the Verizon one that just uses the flexibility of the molded plastic.
