There is a possibility that the mobile phone disconnects during the extraction. This is a known issue of the iPhone with a large amount of data when the phone may stop answering communication requests. If that happens, there is no need to worry, MOBILedit is capable of continuing in suspended extractions. When this occurs, all you need to do is physically reconnect the phone to your computer. MOBILedit will automatically continue with the extraction, and no data will be missing.
