According to Macworld, iPhone 4S’s sold by Sprint will come GSM-unlocked. Verizon’s version can be unlocked after 60 days. What that means is on your next trip to Vietnam, there will be no need to jailbreak and unlock your iPhone, a process that can be complicated and could void your warranty. This feature is huge for the thousands of Vietnamese Americans making the pilgrimage home to Vietnam every year. In fact, it’s huge for any of the 60 million Americans who are 1st and 2nd generation immigrants.
As for AT&T iPhone 4S owner, you’re out of luck. AT&T runs on a GSM network here in the US so they are well intent on locking the SIM to keep themselves the exclusive GSM carrier.
The iPhone 4S, though debuting as a disappointment to diehard fans due to lack of significant feature updates, is becoming the fastest selling iPhone to date. Apple has already reported 1 million units sold since the phone was announced last week.
