Isn't there an app for that?

As in... has no-one created an app showing a real-time scrolling graph of reception level and an accurate (or as accurate as possible) number of the current reception level... perhaps with an overlay of the number of visible towers and strength?

Because if they did, then not only could it be proved by the layman but if the problem existed then the layman can visually see the effect and visually gain feedback on their techniques to find a better way to hold the phone.

If this doesn't exist, it sounds like a great cash-in app for right now. I'll take 2.5% of revenue for the idea.

I have a great little app for my Android G1 that shows your location on a google map (GPS) as well as the location of the cell tower you're connected to. I suspect Apple don't provide an API for this sort of stuff..

What is that app named? I want it!

CellFinder is one app that does this.

There's also Antennas.

One is called "Signal Radar". I found it by searching for "cell tower" in the market, first hit.

I use cellmapper.
