Sony recently made the Xperia Z available for sale in the U.S. from its online store. The Xperia Z being offered by Sony supports HSPA+, but not LTE 4G networks.
The full retail price of the Z is $629.99. The FCC recently approved a version of the Xperia Z that includes support for T-Mobile USA’s LTE network, but Sony is not selling that variant yet.
Additionally, Sony dropped the price of the Xperia ZL, also available from its web store, from $759.99 to $629.99. Both the Xperia Z and ZL are being sold unlocked and without carrier contracts.
