For those of you with Windows Phone 7 devices, you are likely acutely aware of the 10-15 second lag when switching between applications.
XDA forum member Jaxbot, has posted a registry key hack that resolves the issue. The hack allows you to switch between applications without having to wait on the ‘Resuming…..’ message and requires the DehydrateonPause key to be disabled.
There are however, some side effects – notably you may experience faster battery drain, and there have been issues reported with the camera app locking after applying this tweak.
For more information including details of the registry key, head on over to the modification thread._________
