WP7 Instant Resume Via a Registry Hack

"When exploring around in the Windows Phone 7 registry, our main developer Jaxbot found something interesting. After playing around, the results were instantly evident: Instant Resuming on Windows Phone 7...Quite simply, this hack disables the "Resuming..." phase when returning to an application, and instead will take you right back to where you were, instantly."

Windows Phone Hacker has posted instructions on how to edit the WP7 registry to enable instant resuming of applications.  When applied, the "resuming..." phase is disabled and thus you will be able to immediately return to your application when switching between apps.  According to the developer, this edit "disables the dehydration function of the task host" and brings some "undesirable but not crippling" effects.  

If you are of the daring type and want some of the instant resuming action, take a look at the instructions and give it a try.  The video posted above is a demonstration of the results.  

As with any hacks, your mileage may vary and do so at your own risk.  Let us know if you do give it a try and what your experiences were.
