We've just received word of a spicy strategy change, to be enacted this Sunday, that's sure to please the AT&T iPhone-loving masses. On Easter, select Ma' Bell customers with iPhones -- those with off-contract accounts in good standing -- will be able to request a carrier unlock for their device. Once freed, any micro-SIM can be used -- provided its carrier's frequencies are supported -- by the smartphone. An AT&T spokesperson was able to confirm that "a policy change concerning iPhones" would indeed be rolled-out on Sunday, but declined to elaborate further. That sound you hear?
