Great news for all of you traveling folks out there who enjoy an iPhone that you can use internationally. Sprint has announced that the iPhone 4S will come with a micro-SIM slot unlocked and Verizon’s phone will be initially locked but apparently after 60 days of good standing with Verizon you will be able to call them and have the phone internationally unlocked. So what this means for all you travelers is cheaper international roaming if you acquire a prepaid SIM card for the country you are in. Now the question is what will AT&T do? There is no news yet on them doing any type of unlocking the 4S. If I was AT&T I would make sure that feature is at least an option.
