At 3.55am Pistorius called his friend Justin Divaris for 123 seconds. At 4.01am he called Heinrich Pistorius (his brother, usually known as Carl) and then his manager.
Moller: [Then] three more calls. There was then an incoming voice call from that number to the accused's number and lasted for 49 seconds.?
Nel: We then have GPRS connections.
Moller: Yes … The phone was in that area until about 8am that morning and there after it left.

Chart appears to show #OscarPistorius accessing the internet from his phone twice in hour before midnight.
