From yesterdays article I did tell you that rumors were about the iPhone being unlocked well the rumors are true. The Apple store has the unlocked GSM iPhone 4 at the lovely price of $649 and $749. The 16GB and 32GB versions will be on sale. As with unlocked iPhones sold internationally, the device will work on all Apple-supported GSM networks around the world. Apple also takes care to note that an iPad 3G micro-SIM card will not work in the unlocked iPhone 4.

In the U.S., customers with unlocked GSM iPhones can choose from AT&T and T-Mobile, though data transmission on the T-Mobile network will occur over the slower EDGE protocol because the carrier’s 3G network is incompatible with the iPhone.
