Oscar Pistorius prosecutors say they have secured a meeting with officials from Apple to access potential evidence on the athlete's iPhone.
Pistorius has claimed he forgot the password on the mobile phone, one of a number found at his house after he killed girlfriend Reeva Steenkamp on February 14, 2013.
National Prosecuting Authority official Nathi Mncube says investigators will meet with Apple in the United States later on Thursday through assistance from the FBI.
Mncube says of any possible information on the phone: "it can only add to the evidence we already have".
Prosecutors maintain Pistorius had a fight with Steenkamp before killing her and information on his phone may shed light on events before the pre-dawn shooting.
The prosecution will make any evidence from the phone available to Pistorius' defence lawyers.
