You would need to jailbreak the iPhone and use MyWi to turn your iPhone into a WiFi hotspot. Then the PlayBook can connect via WiFi. (As far as I remember, the native hotspot feature is only available on the iPhone 4 and 4S. Might want to double-check that.)
You won't be bridged, so your PlayBook will be pretty limited in functionality.
For bridging, you need a compatible BlackBerry handheld.
