If palmOne won't step up to the plate and add WiFi to its handhelds, it's only natural that someone else would do it, right? Someone already hacked the drivers for palmOne's SD WiFi card so it'd work with the Treo 650, but we pretty much figured that the Treo 600 was a goner. Not so. It's not quite as svelte as getting down with a WiFi card, but Enfora is introducing a WiFi sled for adding 802.11b to the Treo 600. They'd already done one of these for the Tungsten E, and this one looks like it's along the same lines.
