IE6 - Integrated Google Search (WM 6.5 or higher)
I just read through the Mobile Browser Comparison here
on XDA and noticed that one of the points for Opera Mobile over IE was Integrated Google Search.
Perhaps this is not well know, but IE has the option of integrated Google search as well.....
Internet Explorer 6 Mobile - Integrated Google Search
By default Microsoft configured IE6 to use Bing as the default search engine.
*note: Prior to WM 6.5.3, m.live.com was used, but it now re-directs to m.bing.com anyway.
Type 'xda forum' in the address bar and then enter and you will see that after a short timeout (once IE determines that 'xda forum' is not a valid address) it will show the search results using Bing.
Making the change
This is easily changed to Google by modifying this registry entry....
To avoid waiting for IE to determine that your search terms are not a valid address, simply choose ' Search for "......." ' from the drop down menu that appears as you type....
I have included CABs which will make the change for you if you feel uncomfortable making the registry changes yourself.
Finally, if you like using the default home page included with Windows Mobile (\windows\iemo6_default_0409.htm - depends on language and often changed by OEMs and cooks), I have included an updated version of iemo6_default_0409.htm that uses Google instead of Bing.
