The iPhone uses a new version of WebKit than ships on the Mac (unless
you install a WebKit nightly, or are using the Safari 4.0 beta).
You can confirm this using the jsc command-line program (built with
WebKit). In earlier versions, it would support the 'return "hello";'
example as expected, but the new Squirrelfish (or whatever it's
advertising name is nowadays) will not.
If you just change to Peter's formulation:
"(function () {return "hello";}) ();"
... everything should work as you expect.
Think of it as future-proofing your code for Safari 4.0! :-)
