We've seen auto-hangup apps and even applications to answer your phone by waving. Now here's something you will probably use more frequently: An application that actives your loudspeaker as soon as you move the phone away from your face. Developed for the HTC HD2, XDA forum user zevele has created an application called Zevele's AutoLoudspeaker v1.2 that reads the proximity sensor of your device to see if your phone is away from your face or not. If it is, it will activate speakerphone automatically. The application looks solid and there are several planned features that may be added.
