You received a letter saying that your IPhone Unlocked?
What do next?
If you're in range of a Wi-Fi activate iPhone, simply connect to a wireless network and follow the instructions on the screen. All your iPhone activated and ready to use!
If Wi-Fi is not around, you can use your PC or Mac. In this case you must do the following:
1. Go to the site Apple.com and download iTunes.
2. Install it.
3. Connect iPhone to your computer. (In rare cases you need to reset the network configuration Settings/Basic/Cellular/Reset/Reset network settings)
This activation ends.
Congratulations, Your iPhone is unlocked!
