In case you missed it, Opera Mobile 10 beta for Windows Mobile has been released. The mobile web browser closely resembles its sibling, Opera Mini 5, with a touch friendly interface. Like with any program in beta, there are some bugs and missing features. To the dismay of many, especially users with slab devices like the HTC HD2, auto-rotation was not included in the beta. This feature was present in previous versions of Opera Mobile and it enabled users to automatically rotate the browser by using their device’s built-in accelerometer.

All is not lost, as there’s a way to get the feature back. You’ll need a registry editor like the one found in SKTools (screenshots below) or Total Commander (free). Follow the directions below precisely and you’ll be set to browse the web in landscape mode again.



Registry fix to enable auto-rotation:

1) With a registry editor, navigate to: “HKEY_CURRENT_USER (HKCU) \ Software HTC HTCSENSOR GSensor ModuleName”

2) From there, add a string with the name “Opera10″ and string value “Program FilesOpera Mobile 10Opera10-armv4i.exe”

3) Then navigate to: “HKCU \ Software HTC HTCSENSOR GSensor WhiteList”

4) Add a string with name “Opera10″ and string value “OM10-ML-MainWndClass” (Please note that Whitelist string value is case sensitive!)

5) Finally, you will need to soft reset for changes to take.

Warning: the registry additions were made with Opera Mobile 10 installed on device memory, not storage. Only make these changes if you’re comfortable using a registry editor. It’s also a good idea to backup your registry beforehand. Not confident in your registry editing skills, but want to learn? Read Anton’s Windows Mobile registry editing guide.

Update: a CAB is now available on XDA-developers for easy installation (thanks for the tip, HTCeros)
