We were kicking around this idea for a while. There are some problems that we faced with this when trying to build a generic application: (a) Many (most?) phones do not give a J2ME programmer easy access to GSM data (cell ID, LAC, signal strength, etc.) for all visible towers, though these data can be obtained through serial AT commands, (b) It is much easier to get GPS data, say from an external bluetooth GPS device into a J2ME application running on a phone (requires JSR179) None of these apply to OpenMoko, so I can easily envisage an application that maps cell towers by sending GPS + GSM data to a central server over GPRS, or SMS, or storing these data, and syncing it once in a while. If there is interest in this, we would be glad to collaborate on a solution.
