If you've been holding out for AT&T to release the Samsung Galaxy S II Skyrocket HD you can now give up the dream and move onto the Samsung Galaxy S III. As confirmed by Samsung's Ryan Bidan, the Samsung Galaxy S II Skyrocket HD has been put to rest on AT&T due to the fact that it just doesn't make sense to release the device now that the Samsung Galaxy S III is out there.
Although Bidan stopped short of confirming that AT&T would see a release of the Samsung Galaxy S III, at this point it's pretty much assumed or in Bidan's words it'll be coming to "the fastest HSPA+ and LTE networks" in the country. That doesn't leave a whole lot of options and surely, AT&T will want to fill that gap.
