As defence lawyers we spend a lot of time working out issues about our clients’ mobile phones;
- Who do we subpoena to get information for a particular number?
- Where were they at a certain time? (what tower were they near when making calls)
- Who have they been ringing?
- Who has been ringing them?
I came across this very useful list of mobile phone acronyms which I have added a couple to.
