must have android application for hold sanity

Sure, mid conversation one could mash the speaker button and switch the call to speakerphone while on hold

…. but there is a f/OSS application [on google code] that uses the proximity sensor to do this automatically for you.  What’s more is has a toggle switch to engage only when phone is set upon a mostly horizontal surface:

Take phone from face, set on table… voila speakerphone on hold

there be one gui bug: speaker button does not illuminate when the application toggles speakerphone on by proximity sensor

Plays well with IMSdroid
