http://www.bbc.co.uk/news/technology-13874818BBC to survey UK mobile coverage
"The BBC is conducting a major survey into the state of mobile phone coverage in the UK.
Over the course of the next month, the project will attempt to chart the availability of 3G and 2G services up and down the country.
Mobile operators offer their own coverage maps but no independent survey has yet been carried out.
Measurements will be made using an app developed by network analysis firm Epitiro."
If you have any privacy concerns read the licence and remember the phone company knows where you are every 5 seconds or so anyway.
