I think it's pretty clear from the SDK License that Apple will not be supporting any type of 3rd party kernel extension... at least for the foreseeable future if ever. The SDK license strictly points out that the only code that will be allowed to enter into a customer's iPhone/iPod Touch is code that only uses the public API. Any code that uses unpublished API will be rejected. Since there is nothing there for Kernel Extensions I think the writing on the wall is pretty clear.

I think this is a huge win as Apple can change things internally as much as they wish and that really cool application that everyone uses will not be affected because it wasn't allowed to use some of the stuff that changed. As well, it ensures performance and stability. The two things that are probably the most important to maintain on a mobile device.

I can understand Apple's point of view, but it also means some interesting
applications can only be written from inside. Here's an example:


I'm the developer of a Macintosh software router/AirPort gateway and
would love to build an app to allow your iPhone to act as a Bluetooth
modem or AirPort Access point for when the G3 iPhones arrive.

I can imagine a cell-connected base station being rather popular on
long car trips with laptop equipped passengers.

Will Apple do it? Is there any way I could do it?

In addition to this potential limitation in the SDK (whose contents does not officially exist), I tend to believe there's also a restriction from the carriers and Apple. As of today, I don't think you're entitled to use an iPhone as a modem. And anyway, AFAIK, you can only use the Bluetooth feature for the iPhone Headset.


And if we are to believe the claims regarding battery life with WiFi and G3, I'm not sure how long a car trip could be in this case without an external power source.
