We'll likely never know what's driving this purported move, but we can safely imagine it has something to do with the cost of high-end devices like that Galaxy Nexus or HTC EVO 4G LTE. Either way, a recent report by the folks over at TechnoBuffalo suggests Sprint is about to switch its Total Equipment Protection plans to a tiered-based system. The adjustments, which are said to take place as soon as June 17th, will see the TEP and ERP (Equipment Replacement Program) prices change to $8 and $5, respectively, for slabs under $550, while any device -- including the aforementioned couple -- over that amount gets an $11 TEP and $9 ERP fee. As you can tell by the picture above, deductibles have also taken a hit, ranging anywhere from $50 for Now Network devices worth less than $325, all the way to $200 for those over $600. Of note, iPhone owners need not to worry, as Sprint's still holding you to Apple's careful insurance.
