Google Maps has a feature somewhat like this. Look at

We were kicking around this idea for a while. There are some problems<br>
that we faced with this when trying to build a generic application:<br>
(a) Many (most?) phones do not give a J2ME programmer easy access to<br>
GSM data (cell ID, LAC, signal strength, etc.) for all visible towers,<br>
though these data can be obtained through serial AT commands, (b) It<br>
is much easier to get GPS data, say from an external bluetooth GPS<br>
device into a J2ME application running on a phone (requires JSR179)<br>
<br>
None of these apply to OpenMoko, so I can easily envisage an application<br=
