Guess this is Sprint’s big announcement. Effective tomorrow, Sprint will offer a”Sprint Free Guarantee” on all contracts. Anyone who inks a deal with the Now Network will be able to walk away from it within 30 days and not have to pay any sort of fine. All you have to do is hit them up and let ’em know you don’t want to continue the relationship and return your handset. For being such an upstanding person, Sprint will do so much more than just give you your money back for the phone. They’ll give you back your activation fee, axe the restocking fee, kill off the ETF and, this is a biggie… refund your entire month’s service including surcharges and taxes. We’d say this has a more than good chance of quickly being copied by AT&T, T-Mobile and Verizon, but clearly they’re not desperate enough to risk implementing a policy that looks to be painfully easy to exploit.
