Can a WiFi-only Kindle connect to the internet through an iPhone?
You have to jailbreak the iPhone and install an expensive program called MyWi 4.0 (check spelling) from Cydia. This allows the iPhone to host a wifi network that a Kindle can connect to.
Ask if you need more details, I'm on my iPhone now so don't want to type much :)
