Today I wanna introduce a useful app in Android Market-OpenSigalMaps.
It’s developed by Staircase 3-the team also invents quite a number of other websites,products and services.This project-OpenSignalMaps,is wanting to gather the cell information over the world together and then take out into a map that everybody could utilise the information to decide which mobile service provider you’d better to choose or why my cell signal is so weak and how to improve it.
