• It works with the SIM Toolkit menu on the device and you don’t have to even reboot the phone to get it working. 
• It works only with the iPhone 4 on firmwares 4.00,4.01,and 4.02 .The Adapter comes with a case which stores the SIMs. 
• It does not look too attractive and there’s no dual standby support but seems like it does the basic job very well.
• It costs $28.99
