Much like we saw with the HTC One, carriers are quick to ride the wave of hype that manufacturers are creating. AT&T and T-Mobile launched pre-registration pages for the Samsung Galaxy S4, but with no detailed availability or pricing. No real surprise there.
Sprint also released a statement regarding the S4, assuring their customers that they too will offer the device. Once Sprint and Verizon make registration pages (if they do), we will update the post for you.
