trawling the location records should be easy - once the phone companies have been forced to release them. Remember you don't need to prove who read what, or who sent what. All you need to know was who was when, and where - and match that with video footage and still photography
Face recognition software is getting good enough so that you can cross-match people from one location to another (that is standard Face-book capability now) in videos and photos
Once you identify the phone numbers of interest, then you can start reading the texts. Echelon will have the simple texts on record, while Blackberry say they'll co-operate over their encrypted BBS messages. Faceb00k/Twitter messages should be discoverable through the DNS servers records - and by reading the phones internet browser cache remotely (this again can be activated without the user knowing)
Then you have to ID the user. If the phone is on contract, then you've got a billing address. If the phone is purchased anonymously then it can be tracked in real-time by the location methods stated earlier. And can be intercepted by SIGINT/ISTAR aircraft
Even if the user changes the SIM card the phone can still be tracked in real-time through the other identifying codes

WTF does Faceb00k get changed by the system software to Facebook? What **** thought that one up?
