Meanwhile, Sprint Nextel will offer the phone for $250 up front, with a $100 credit for any customer who switches from another carrier. Sprint's verison will go on sale beginning Saturday, April 27. 

AT&T customers can now pre-order the device for $199, with shipments starting April 30. As of this writing, Verizon Wireless has said it will carry the phone but it had not yet confirmed pricing or availablity for the S4. 

Regional carriers C Spire Wireless and U.S. Cellular also said they will be getting the S4 this summer.
