It was revealed last week that the Galaxy S 4 would be available for pre-order with AT&T on April 16. It was assumed that the launch would come sometime in May, but a new leak suggests that we could be seeing Samsung’s latest flagship device hit retail, at least in Europe, in late April.

SamMobile received a leak that says Samsung will start shipping the 16GB Galaxy S 4 3G in two weeks. The leak says that the shipments will hit Eastern Europe, Russia and the Ukraine first.

What’s disappointing is that it seems the 3G Galaxy S 4 will be released first with the LTE S 4 scheduled for the week of May 19. If that’s the case, we could see the 3G variant of the Galaxy S 4 released before the LTE variant in the U.S. as well.

Beyond AT&T’s announcement, there’s been no other carriers announcing pre-order plans for Samsung’s latest flagship device. At T-Mobile’s Un-Carrier event, the carrier said that the S 4 would be available on its network in May. AT&T would most likely get it before T-Mobile so an early May release in the U.S. seems likely.

We may still see the S 4 launching in the U.S. in late April, but FCC regulations may prevent us from seeing the S 4 before our friends in Europe get their hands on the device. Either way, it’s only a few more weeks until the Samsung faithful will be able to get their hands on the S 4.
