Lightning unofficial cable trick for iOS 7
It may be a hint to you if you are buying an iPhone from a second hand without accessories.
You will need TADAA! Official Apple cable but not for a lightning port. And another Apple device.
The thing is if you connect both your new iPhone or iPad via lightning port and using unofficial cable and ANY of your Apple devices using OFFICIAL Apple cable. It will trust your lightning connected device.
Some magic happens and one device connected with official apple cord makes another device connected via official cord too.
TADAA. Now you can sync at least once... and use Wi-Fi sync later on...
Hopoe it helps you. Comments?
