iPhone development without spend 100$

If you, like me, just want to learn how to develop applications for the iPhone (and with luck even create one) but don't want to spend 100$ of the apple program for developers, There are very clear instructions in 246nt.com (http://www.246tnt.com/iPhone/), maintained by Sylvain Munaut, about how to use XCode with a Pwned iPhone and be able to make Build&Go and also debug the program in the terminal (this work from firware 2.0.0 to 2.0.2, as far as I know).

The process is easy to follow, but you need SSH access to the iPhone and also hack the iPhone installer and the SpringBoard (also included in the instructions).

There are very clever people out there.

Update:
A new page: http://hackint0sh.org/forum/showpost.php?p=342736&postcount=53, specially the trick in the Info.plist is needed to don't have problem launching the application, avoiding the message "The application XXXX cannot be opened".
