Car phone Warehouse has now started accepting pre-registration for Samsung upcoming flagship. However, no name has been mentioned by the retailer except unveiling it would be New Samsung flagship and allegedly with moniker Galaxy S6. Apart from S6 the UK retailer has also started accepting pre-registration for HTC next flagship. It is the currently unveiled New HTC One, and will be dubbed as HTC One M9.We should definitely understand the difference between pre-registration and pre-order. Pre-registration is people showing interest in the device only and pre-order means reserving a unit for oneself. Both flagships are expected to unveil on March 1 at MWC in Barcelona.
