How to unlock iPhone 3GS ?

Network unlock for an iPhone 3GS doesn't use a code or unlocking sequence. The device is remotely unlocked on Apple servers.
There are two types of instructions for iPhone 3GS.

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 3GS is ready to work in any network.

Second option (if the Wi-Fi option doesn't work)
1. Connect iPhone 3GS 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 3GS is now network free.

The easiest way to check if iPhone 3GS is permanently unlocked is by inserting a different simcard (from different networks).

I was a bit sceptical at first but because of the positive feedback I decided to have a go to unlock a 3GS ip from Singapore. I have followed the instructions but nothing happen at first and I was about to feel let down...but then after 20 to 30 minutes of trying on the iTunes Store slowly it began to detect my device and to my delight my network starts to appear This a joy for celebration I can use my Favourite 3g design iphone. FANTASTIC SERVICE AND IT ONLY DELIVERED IN ONE DAY A BIGGGGG THANK YOU
