To make matters worse, those Windows Phone 8 users in India that downloaded the GDR2 update on their handset found that after installing the update, they lost the option to replace Bing as the default search engine on their phone with Google. Keep in mind that this doesn't prevent a Windows Phone user from just typing in www.Google.com to access the search engine from the browser on the phone. It's just another pain in the butt forcing you to make additional keystrokes. Of course, Microsoft is hoping that you will decide to give up and just keep Bing as your default search engine on Windows Phone 8.
