(different search engine strings on SDK on the left, Firefox 3.6 for Mac on the right)

Here's some more interesting information from the iPhone OS 3.2 SDK. Users will be able to set search to something besides Google in the search bar of the iPad's Safari in upcoming iPhoneOS releases.

Right now, the two options besides the current default Google are Wikipedia and Yahoo, but plugins could be developed to do things like Amazon and Bing searches directly from the search bar in the Safari browser.

There is even a suggestion manager for both Google and Yahoo depending on which search engine you choose. Unfortunately, no Bing… yet.
