Thanks, useful link.

I don't know for sure whether mobile service providers are required to 
retain location data for internet sessions under the 2009 regs/DRIP - 
personally I'd have said no, they do not, but others may disagree.

The meanings of "mobile telephony" and "communication" are in question, 
and who knows what a Judge might say?, they seem to make it up as they 
go, and usually in favour of the Establishment.

Though perhaps Three agree with me?

However, mobile service providers are free to retain as much location 
data as they might want to, under ACTSA.

I would be interested in any more information you can come up with. Or a 
link to your paper, if you write one.
