From pcworld.com:

The ability to charge without wires is an idea that’s been teasing us for a long time, with Palm the first company (I am aware of) to take it mainstream. The feature will soon be available for iPhone users, too.

The iPhone solution, from WildCharge, requires placing the iPhone or iPod touch into a gel skin inductor that looks pretty much like any other form-fitting other case. It includes a small connector that plugs into the iPhone. Once installed, the user places the iPhone onto any WildCharge charger pad and the phone starts charging.

The iPhone charging skin and charger pad combination costs $80, while the Pre wireless charger is a $70 add-on from Palm. One important difference: The WildCharge pad and skin are part of a system that works with other devices, such as the BlackBerry Curve and Pearl as well as the Motorola RAZR phone.

The iPod touch skin is available now, with the iPhone version available “in early July,” WildCharge officials said.

$70-80 is a bit much for the ability to simply plunk down your phone on your desk instead of taking a few seconds to plug in a cable. But I’d imagine it’s only a matter of time before the iPhone and other devices come with the wireless charging ability out of the box.
