Zires and cellphones don't mix?

We haven't seen anything official on this yet, but over the past few months a significant number of people have noticed that keeping one of palmOne's Zire 21 in close proximity to a cellphone causes the memory on their Palm to get erased. The physics of all this is way dodgy, but enough people have complained about their Zires getting wiped that there's a good chance there's some sort of problem with the RAM in these things whether it's cellphone-related or not.
