It turns out it was a mistake. Best Buy has issues a correction notice stating that the phone was incorrectly labeled as the Samsung Nexus Prime and the Samsung Nexus Prime 4G LTE. The correct name is the Galaxy Nexus by Samsung – 4G LTE. Best Buy also says that the device's status is “Coming Soon” and, therefore, is not currently available.
Best Buy also notes that the listing of the “RezoundT by LG” should have been written out as its official name of “HTC RezoundT – 4G LTE.” We are assuming the ‘T’ is in place of the trademark symbol.
As with any adverting kerfuffle, Best Buy goes on to apologize for any confusion or inconvenience, or in layman’s terms “whoops.”
