Normally I’d write this up as an iPhone Application Idea but I think
it’s actually better suited to Android where it could run as a
background process.

Here’s the idea. Build a lightweight app that snapshots location (via
GPS) and 3G signal strength every ten seconds or so (possibly varying
sample time according to velocity) and submits the data to a webserver
that collates input from multiple users to build a detailed, high-res,
constantly updated map of 3G signal strength. Superimpose the results
on a Google Map and publish it for the greater good.

I haven’t checked to see if this is a) possible or b) original, but
I’ve been thinking about it for a while and I just wanted to get the
idea out there.
