Once the iPhone 5 comes out, I'm planning on switching from the iPhone 3GS to the iPhone 5. When that happens, my iPhone 3GS will no longer have an active SIM card. Will I still be able to access the features on the iPhone, such as Wi-Fi, Music, and other apps such as games? I won't need the Messages or Phone apps.
>>> Can the iPhone 3GS function as an iPod Touch if I remove the SIM card?
