问题 I would like to implement a application which backs up all the internal data like SMS, MMS, videos, audios, documents, call history stored in iPhone. But this seems to be not possible with API docs that the apple has released so far ... I have gone through the PDF of Enterprise distribution program and some of the links related to Enterprise Distribution Program, specifies about the Remote wipe and accessing of internal data like Calendar, SMS, MMS etc .... But they didn't mention how to do
