The entire Dev Team makes a good bit of $$ from donations. However a majority of people don't donate unfortunately If every person who jailbroke their device donated 1-2 dollars, they'd be set. Fortunately for all the tight-wads out there, a lot of these guys do this stuff for the challenge and for fun and I doubt we'll see them put a price tag on JB's any time soon.

Yes I did. Normally everything I have ever seen was no donations off iPhone dev's website. Very much worth it and helps with school expenses too. Would hate to be graded on a curve with him in my class lol.
