Not developed specifically for the iPhone, but a great resource for it!

<em>Overview:</em> Mogoso allows you to research a product and get reviews when you need it most: when you're out shopping, in the library, or renting a movie. The sites designed to work on modern smart phones like windows mobile, blackberry and treo.

Example: Maybe that movie "The Ice Storm" is your kind of thing, but you're not sure. Via your phone, just go to www.mogoso.com, search for "<a href="http://mogoso.com/results.aspx?search=the%20ice%20storm">The Ice Storm</a>" (or its UPC code "<a href="http://mogoso.com/results.aspx?search=024543012245">024543012245</a>"), and there you go! On top of that you get its price on amazon.
