Here is a little easier unlock solution for your iPhone 4, by using this little SIM unlock card. It requires no hassle of having to use any of the jailbreak and unlock tools such as redsn0w, ultrasn0w from the iPhone dev team. And using the SIM unlock card is a more straightforward way of unlocking your iPhone 4, without having to deal with complex software tools or voiding the iPhone 4′s warranty.
Basically the iPhone 4 SIM unlock card is a very thin piece of FPC (0.10mm) with a Microcontroller mounted on, which goes between your SIM card and the iPhone’s SIM socket. It’s said to be slim enough to fit your iPhone 4′s SIM socket. But you’ll need a little cutting of your operator’s SIM card.
The iPhone 4 SIM unlock card is available on USBFever for $30. There are a number of steps including having to turn on and off AirPlane mode, while using the unlock card to unlock your iPhone 4. Please read carefully the step by step instructions, the supported versions of iOS and basebands on USBFever. Hmmm, do it at your own risk!
