Is it possible to buy a warrantied and supported unlocked SGS4 Mini in the USA? I see sellers of the GT-I9195 on Ebay with unlocked phones that say no manufacturer's warranty and I assume also no-one to upgrade the Android from time to time. My phone is the Google edition of the SGS4 which is an ideal kind of offering, but wifey says that device is too big for her. Any suggestions? In Europe I know I see that I could get one from Carphone Warehouse. Is there anywhere like that over here? Would Best Buy or Costco sell such a configuration with Samsung support?
