From ESPN
"Sprint is excited to launch the new Samsung Galaxy 4. We had
planned to launch this next generation of the award-winning Samsung
Galaxy line-up on Saturday, April 27. Unfortunately, due to unexpected
inventory challenges from Samsung, we will be slightly delayed with
our full product launch. Sprint is one of Samsung's largest partners
and we are working closely with them to launch in all Sprint channels
as soon as possible. We expect to make GS4 available at
www.sprint.com
and Telesales (1-800-SPRINT1) as planned on Saturday with Sprint
retail stores and other channels receiving devices as inventory
becomes available."
"Due to overwhelming global demand of Galaxy S4, the initial
supply may be limited. We expect to fulfill inventory to meet demands
in the coming weeks."
