How to unlock iPhone 4 ?

Network unlock for an iPhone 4 doesn't use a code or unlocking sequence. The device is remotely unlocked on Apple servers.
There are two types of instructions for iPhone 4.

First option
1. Insert a simcard from a different network than the one working in your device.
* the unaccepted simcard cannot ask for a pin code at the start. Please use a simcard that doesn't ask for a pin, or turn the request for a pin code off.
2. Start the device and turn on Wi-Fi
3. Small update should be downloaded.
iPhone 4 is ready to work in any network.

Second option (if the Wi-Fi option doesn't work)
1. Connect iPhone 4 to the PC by cable with an unaccepted simcard insterted (simcard from a different network than the one where you bought the device)
2. Start iTunes application on your PC
3. Small update will be downloaded.
iPhone 4 is now network free.

The easiest way to check if iPhone 4 is permanently unlocked is by inserting a different simcard (from different networks).
If iPhone 4 comes from AT&T network and you insert Sprint carrier sim card and a message "iPhone has a simcard from a different network" or "incorrect simcard inserted" appears on LCD it means that the device is network blocked.
However if the device has a signal and you can make calls or send text messages iPhone 4 is unlocked.

If you don't have a simcard from a different network or you don't know the original network, you can use this service which helps you check your iPhone carrier and country check for iPhone 4.
iPhone 4 can be permanently unlocked by adding the IMEI number to its producer's database.

This worked. My wife had an iPhone 4s, we got it to use as iPod only. then decided to get it working only to realize it was locked... so had no choice but to start searching out how to unlock it. this for us took 2 business days basically. Seemed to work no problem.

Zgodzę się z wieloma wcześniejszymi opiniami użytkowników : Bardzo szybko i sprawnie przebiegł proces odblokowania mojej karty sim/telefonu nie ruszając się z domu. Jest też taniej aniżeli w salonach sprzedaży telefonów.
