Pocketnow reports on an application which allows you to wake your
HTC HD2 from suspend simply by shaking it.
The software stays active even when the smartphone is suspended, and also keeps the G-sensor awake. The effect on battery life is not known yet, but if you decide to try it out, let us know in the comments below.
The software by zzattack can be downloaded from this
XDA-Dev thread here.
It was originally developed for the HD2 but I tested on my TP2 and it works as it should. It's not a cab file, You select the exe and it works. To uninstall you just end the process.
