Iphone Undocumented/Private API vs. Toolchain
<p>Excuse me if this is a "sparse" question but, I'm somehow confused wit the terms of "Undocumented API call" and "Toolchain" (of Saurik). </p>

<p>Are they same? Or toolchain is "yet another wrapper" for Undoc. APIs? Or entirely different things? </p>

<p>And what place does Erica Sadun's work sit in these definitions? </p>
