The firmware isn’t out yet for the 3GS or 3.0 OS for iPhone 3G for the Rebel Simcard.
From our testing so far, we have found out that Apple have changed the simgate in the new iPhone 3G S, So it will no longer physically accept any No Cut Unlock simcard. So do not try to force it in as will get stuck.
Rebel are designing a new No Cut version of the Rebel of the Simcard, This will be released as soon as possible.
Still the good news is the current universal Rebel cut sim can still be used to insert it along with a network simcard.
The Rebel Simcard R&D Team are working on the unlocking solution for the iPhone 3G S model and iPhone 3.0 Firmware.
