Hello AlishaM,
Thank-you for your question.
Basically Zap considers to be one of Apple’s Partner, that means Zap has special privileges and option to use Apple’s devices which non-Apple partners do not have (See following Zap’s Partners list at http://www.zaptechnologies.com/why-us/partners).
Based on the above ZAP offers 3 different options to configure any Apple mobile device:
The rooted option, The instrumented option, The ZUMA option(ZUMA = ZAP Universal Mobile Access).
To explore more how Zap-fix configures iPhone, please contact Zap and get the Zap-Fix Evaluation license at:
