Hardware unlock for iPhone 3G
Usbfever announced iPhone 3G
This SIM unlock is made of a very thin piece of FPC (0.10mm) with a Microcontroller mounted on, that goes between your Operator's SIM card & the phone's SIM socket. This SIM unlock is inserted into the iPhone 3G in parallel with your Operator's SIM card and enables you to use your card on phones locked to another provider. Cutting of your Operator's SIM card is required but kept to a minimum.
