I have been using Opera mini since I bought Nokia 6680. I have changed many phones but two things were always common "Nokia" & "Opera Mini". Last year I bought Nokia Lumia 510 running on Windows Phone 7 (latest 7.8) & could not use Opera on this phone and now when it is for Windows Phone it's only for WP8 not for WP7. So I request developers to launch Opera Mini for Windows Phone 7 also.
