Windows Phone 7 has had a rocky path since it’s early release, and despite featuring a snazzy panel interface and integration for Xbox Live, it still misses a few vital additions in the form of copy/paste and multitasking.
We should get the update to provide copy and paste by the end of this month if all goes to plan, but the multitasking aspect is coming out at a later date. If you can’t wait for the official update, a developer by the name of Jaxbot, who works on the Windows phone hacker site, has managed to uncover an instant resume function when messing about in the registry.
What this means is that when you are running a game, for example, it disables the resume function. When you return back to your game after pressing the power button you can go straight back to where you left off, no delay and no fuss. From a technical point of view the process disables what is called a dehydration function of the task host. This makes it possible for the phone to switch between applications without requiring a reload.
However, as with any hack you do need a bit of tech savvy in order to complete the procedure and one important ingredient is certainly required. Your phone needs to be developer unlocked which requires you to jailbreak your device. Once you have done the above you need to edit the registry and look for the following key: HKLM\Software\Microsoft\TaskHost. Once found you need to then change the default value of the DehydrateOnPause function from 3 to 0.
Jaxbot does warn that the hack could cause a few untoward side effects, but they should not cripple your device. Mind you, with the ability to multitask there will be a lot of advanced users trying this out i’m sure.
