The post “Interesting geotags” points out a few cameraphone-specific geotags recently found in use on flickr. The example at http://www.flickr.com/photos/koolwaaij/73566875/ is tagged with:

 celltagged
 cell:signal=63
 cell:mcc=204
 cell:mnc=815
 cell:cellid=47889
 cell:lac=4496

If you have an S60 phone, you can grab these values with a simple Python for S60 script that uses the Location and Sysinfo modules. The most basic script, which simply dumps the value to the console, looks something like this:

import location
import sysinfo

mcc, mnc, lac, cid = location.gsm_location()

print u"celltagged"
print u"cell:mcc=%s" % (mcc)
print u"cell:mnc=%s" % (mnc)
print u"cell:lac=%s" % (lac)
print u"cell:cellid=%s" % (cid)
print u"cell:signal=%s" % (sysinfo.signal())

And if you’re curious, this post was made from:

 celltagged
 cell:mcc=244
 cell:mnc=5
 cell:lac=9000
 cell:cellid=9953
 cell:signal=7
