The developer known as Jaxbot is becoming quite familiar around these parts, who's known for bringing instant app resuming and multitasking to Windows Phone -- long before these features had gone mainstream. Now, he's back at it with WindowBreak, a project that seeks to deliver an interop unlock tool that can be used on any Windows Phone. As you can see in the video after the break, his tool already works on Samsung phones, and now, Jaxbot needs the help of like-minded hackers to perform similar feats with HTC and Nokia handsets.
